The Future of Software, According to Replet: Agents, Infrastructure, and Why Application Software Trends Toward Zero
Why this matters now: The rapid maturation of AI agents is colliding with full-stack developer tooling in the cloud, pushing software creation from an expert-only discipline toward a broadly accessible capability. In a wide-ranging talk and Q&A, Replet’s founder outlines a thesis that “application software goes to zero,” and that value will migrate to autonomous problem solving, robust agent habitats, and organizational models built for generalists. The discussion spans late 2023 through 2025 (no currency figures disclosed) and focuses on practical agent performance, infrastructure design, and implications for businesses and talent.
Quick Summary
- Agents crossed a utility threshold on SWEBench, with performance now around 70–80% (benchmark saturation doesn’t mean full automation).
- Replet Agent v2 achieves autonomy for 10–15 minutes; v3 targets Level 4 autonomy.
- Near-term “computer use” improvements expected in 3–6 months, enabling deeper end-to-end testing and QA.
- V3 pillars: end-to-end testing, sampling/simulations via reversible FS, and automated test generation.
- Future “Bore Plus”: scale to thousands of agents with ~95% reliability.
- Infrastructure needs: sandboxed VMs, package and language breadth, deployments, databases, auth, secrets, storage, background jobs.
- Roadmap: universal model access and payments (including agent wallets), plus agent-to-agent markets.
- Case in point: HR colleague built an org chart app in 3 days, replacing tools priced at tens of thousands of dollars/year.
- Macro thesis: application software value trends toward near-zero; platforms shift to solving problems, not just building apps.
- Workforce: move from specialization to generalist roles; teams as networks, not hierarchies.
Sentiment and Themes
Topic sentiment (inferred): Positive 70%, Neutral 25%, Negative 5%.
Top 5 Themes
- AI agents and autonomy levels (from assists to near-independent execution)
- Infrastructure “habitat” as the hard problem and core moat
- Reliability via testing, simulations, and computer use
- Software economics: application software commoditization
- Organizational transformation: the rise of generalist operators
From Mainframes to Agents: A New Adoption Curve
The talk opens with a familiar pattern: mainframes required experts; PCs started as toys before Excel made them indispensable. Software engineering followed a similar path—lengthy education and training to proficiency. Replet’s thesis is that we are undergoing the same transition again: software creation is moving from expert-only to everyone. The company’s mission—“solve programming”—oriented them naturally toward AI agents when they began to inflect in late 2023 and early 2024.
Why Agents Now
Benchmarks like SWEBench signal that large parts of software engineering can be automated. While “crappy product today, useful product in two months” is the prevailing rhythm, the acceleration is evident. The coding is the “easy part”; the real challenge is the habitat—VMs, sandboxing, scalability, language/package breadth, shell access, and the services engineers need in production.
The Habitat: Infrastructure as Moat
Replet invests in a production-grade environment tailored for agents: deployments, databases, built-in auth (one-line enablement), secrets, secure API keys, background jobs, and storage for artifacts. Upcoming: universal access to models (with billing handled) and payments—both for user billing and agent wallets to provision third-party services. An agent economy requires agent-to-agent integration and marketplaces.
Levels of Autonomy
Borrowing from driver-assist analogies: language servers (Level 1), code completion (Level 2), early Replet Agent (Level 3), Agent v2 (~3.5). Agent v3 targets Level 4—mostly autonomous with some oversight. The “Bore Plus” horizon envisions thousands of agents executing thousands of problems with ~95% reliability, drastically expanding an individual’s productive leverage.
V3: Testing, Simulations, and Computer Use
Pillar one: end-to-end testing via “computer use” (models operating a computer like a human). It’s slow and expensive now, but expected to improve meaningfully within 3–6 months, shifting QA burden from users to agents and extending continuous work windows to 30–40 minutes, up to one or two hours.
Test-Time Compute and Parallel Hypothesis
Pillar two: sampling and simulations powered by a fully transactional, reversible file system that snapshots every edit. Agents can cheaply fork environments, try multiple solutions in parallel, evaluate, and merge the best back to main—boosting reliability by 2–3x, per the speaker’s projection.
Always-Generated Tests
Pillar three: automatic test generation for every feature the agent creates—continuously run on each change. Models are still weak at unit test generation, and speed matters, but this is central to preventing feature regressions and maintaining coherence over long horizons.
Software Economics: Application Value Compresses
When “one prompt” can create software of any complexity, generic SaaS pricing power erodes. The HR anecdote—building a bespoke org chart app in three days, replacing tools priced at tens of thousands per year—illustrates the disruption already underway. Over “years,” the speaker expects 100% replaceability for many app categories.
From Apps to Outcomes
As application software commoditizes, Replet intends to evolve from “making applications” to “solving problems with software.” Personal examples include quantified-self workflows that should be delegated end-to-end to agents—from specifying goals to acquiring sensors and interpreting results.
Generalists, Networks, and Agent Teams
Work is poised to shift from deep specialization to generalist operators who orchestrate agents and outcomes. Teams will resemble open-source networks more than hierarchies, with individuals waking up to a mission (“make the business work”) rather than a task list. Multi-agent ecosystems will flourish, including domain-expert agents (e.g., elite legal expertise) and agent-to-agent protocols beyond current RPC patterns.
Analysis & Insights
Growth & Mix
Growth drivers concentrate in agent-native infrastructure: sandboxed compute, transactional file systems, broad package/model access, and integrated services (auth, payments, storage, background jobs). Mix shifts from code-assist to outcome-delivery products, which could justify usage-based or success-based pricing. Geographic or segment details: not disclosed.
Profitability & Efficiency
Reliability improvements via simulations and end-to-end testing reduce human-in-the-loop costs and rework, supporting better unit economics for autonomous workflows. Gross margin specifics: not disclosed. Opex leverage depends on platform re-use across many agent verticals.
Cash, Liquidity & Risk
Financials not disclosed. Strategic risks include model dependency, competitive crowding in prototyping tools, and the need for agent-to-agent protocols and payments infrastructure. Mitigation: focus on the habitat and full-stack deployment at scale.

The Future of Software Creation — Agents, Habitats, and the End of Generic SaaS
From benchmarks to business models, here’s how agent-native platforms will reshape teams, careers, and markets — sooner than you think.
Quick Summary
- From experts to everyone: software creation is undergoing the same shift PCs brought to computing — access for all.
- The moat is the “habitat”: sandboxed, reversible, agent-callable platforms (auth, storage, jobs, deploys, model access) matter more than code-gen itself.
- Application software → ~zero: bespoke, on‑demand agents compress generic SaaS margins; value moves to outcomes and platforms.
Introduction
In this NoteGPT brief, we distill key ideas from Replit CEO Amjad Masad about where software is headed. The central claim is simple but radical: writing code is the easy part; building an environment where agents can safely read, write, test, deploy, and roll back at scale is the hard part — and that’s where the moat forms.
As agent capabilities rise, the market shifts from “apps you buy” to “problems you solve.” Teams morph from siloed specialists to generalists amplified by specialized agents, while platform value accrues to those who offer the richest, most reliable agent habitats.
Summary Statistics & Concepts
| Dimension | Today | 12–24 Months | Why It Matters |
|---|---|---|---|
| Agent autonomy window | ~10–60 minutes | ~1–2 hours continuous | Requires testing, checkpoints, and reversible envs to prevent drift. |
| Reliability uplift | Moderate | 2–3× via sampling & simulations | Fork many solutions in parallel; merge the best diff. |
| Generic SaaS value | Declining | Approaching near‑zero | Agents generate bespoke tools on demand; value shifts to outcomes. |
| Team shape | Departmental silos | Networked generalists | Design, product, and engineering blend; domain experts scale via agents. |
| Platform moat | Editors & runtimes | “Habitat” & problem solving | Auth, storage, jobs, secrets, deploys, domains, model access, payments. |
Analysis & Insights
1) The Agent Habitat Is Everything
Masad emphasizes that agent success hinges on infrastructure: cloud‑sandboxed VMs; transactional, reversible file systems; universal package management; and first‑class services (auth, storage, background jobs, secrets, deploys, and domains) that agents can invoke safely. This turns “try, fail, fork, and merge” into a default workflow for machines, not just humans.
2) Sampling, Simulations, and Guardrails
Reliability grows when agents can branch on hard problems, explore multiple solution paths, and run auto‑generated tests at each step. Combined with environment feedback (not just more tokens), the result is longer unattended runs with fewer regressions.
3) From Apps to Outcomes
When an HR professional can build a production‑ready org‑chart tool in three days to match bespoke needs, the writing is on the wall: margins in generic SaaS compress. Platforms must evolve into problem‑solving engines—able to orchestrate resources, pay for third‑party services, and even hire human help on demand.
4) The Rise of the Generalist Company
Agent‑amplified generalists blur traditional job boundaries. Teams begin to look like open‑source networks. The mandate shifts from “ship this ticket” to “make the business work.” Liberal‑arts‑style synthesis and judgment become scarce skills again—paired with scientific habits of testing and iteration.
Practical Playbook
- Build the habitat: prioritize snapshots, rollbacks, CI‑style tests, secrets, background jobs, and one‑click deploys—all agent‑callable.
- Think in branches: run parallel trials on hard changes; promote the best diff after tests pass.
- Empower domain owners: capture HR/finance/compliance judgment inside specialized agents; let generalists orchestrate.
- Price outcomes, not seats: as app value compresses, align pricing to measurable business impact.
- Hire for synthesis: seek clear thinkers who can frame problems crisply and run agent experiments fast.
Conclusion & Key Takeaways
- The moat moves to the habitat: reliability comes from reversible systems and environment feedback.
- Apps give way to outcomes: bespoke agents compress generic SaaS; platforms must solve problems end‑to‑end.
- Generalists rise: roles blend; liberal‑arts judgment + scientific testing becomes a superpower.
Bottom line: the future of software isn’t just more code—it’s agent‑native environments that let ideas compound into deployable systems rapidly and safely.
The Agentic Revolution: Replit CEO Amjad Masad’s Blueprint for a World Where Software Builds Itself
Meta Description: Explore Replit CEO Amjad Masad’s visionary talk on AI agents transforming software creation—from SWE-Bench benchmarks to sovereign individuals. Discover how anyone, anywhere, could soon code without coding, reshaping jobs, economies, and innovation globally.
Imagine a world where your HR manager, with zero coding experience, whips up custom payroll software in three days—saving tens of thousands in SaaS fees. Or where a single prompt spins up a full app, deployed and scaling, while you sip coffee. This isn’t sci-fi; it’s the edge of today’s AI frontier, as painted by Amjad Masad, Replit’s CEO, in a riveting talk on the future of software.
In an era where AI agents are devouring GitHub issues like candy, Masad’s words hit like a thunderclap. For global readers—from Silicon Valley hustlers to Nairobi entrepreneurs—this transcript isn’t just tech talk. It’s a roadmap to democratizing creation. Why does it matter? Because software powers everything: economies, healthcare, climate solutions. If building it becomes as easy as texting, barriers crumble. A kid in rural India could prototype a flood-alert app; a Berlin freelancer might automate her freelance empire. But with great power comes disruption—jobs morph, markets flip, and wealth flows to idea machines, not code grinders. Let’s dive into Masad’s dataset of predictions, benchmarks, and bold bets, unpacking the numbers and narratives that could redefine our digital tomorrow.
Cracking the Code: Key Stats from Masad’s Vision
Masad’s talk is a treasure trove of metrics, blending historical parallels with AI’s rocket-fueled progress. At its core? The SWE-Bench benchmark—a brutal test of AI’s software engineering chops. It pits agents against real GitHub issues from top repos, complete with unit tests and pull requests. Think of it as the SAT for code-bots: solve the problem, pass the tests, or flop.
Here’s the plain-English scoop on the numbers:
- SWE-Bench Scores Over Time: In 2022, agents “barely worked”—scores hovered near zero, like a toddler with a typewriter. By 2023, glimmers emerged; early 2024 showed a steep climb toward automation. Masad pegged mid-2024 at 70-80%—optimistic, but the trend screamed inevitability. Fast-forward to September 2025: Leaders like OpenAI’s GPT-5 hit 65.00%, with Anthropic’s Claude 4 Sonnet close at 64.93%. That’s not saturation yet, but it’s a 300% leap from 2022 baselines, per leaderboard trackers. Implication? What took expert teams weeks now runs semi-autonomously in hours.
- Autonomy Levels: Masad borrows from self-driving cars to grade agent smarts—Level 1 (basic autocomplete) to Level 5 (swarms of reliable bots tackling thousands of tasks). Replit’s Agent v2? A solid 3.5, chugging 10-15 minutes solo but needing human nudges for QA. V3 aims for Level 4: hours of hands-off work via end-to-end testing and simulations. Borg-level (Level 5+)? Expected in 2-3 years, with 95% reliability on mass deployments.
- Market Shifts: Masad predicts application software prices crashing to zero in “years, not decades.” Today, businesses shell out dozens of SaaS tools—averaging $10K+ annually per small firm. Replit’s story: HR pro Kelsey built bespoke onboarding software in 3 days, rivaling $10K/year off-the-shelf options. Replaceable share? From 15% today to 100% soon.
These aren’t dry digits; they’re dynamite. 65% SWE-Bench mastery means agents aren’t toys—they’re co-pilots turning “build me an app” into reality. For a global audience, this levels the field: No Ivy League CS degree needed. A Mumbai mechanic could agent-ify inventory tracking, boosting efficiency by 30-50% overnight.
| Metric | 2022 Baseline | 2023 Progress | Early 2024 | Sep 2025 Latest | Implication |
|---|---|---|---|---|---|
| SWE-Bench Score | ~0-5% (barely functional) | 10-20% (glimmers of utility) | 30-40% (automation trend) | 65% (GPT-5 leader) | Agents solve real GitHub issues; 3x faster dev cycles |
| Autonomy Duration | Seconds (Level 1: Autocomplete) | Minutes (Level 2: Copilot) | 10-15 min (Level 3.5: Replit v2) | 1-2 hours (Level 4: V3 target) | From babysitting bots to set-it-and-forget-it |
| SaaS Replaceability | <5% (niche hacks) | 10-15% (simple tools) | 20-30% (custom prototypes) | 50%+ projected | $ trillions in software spend at risk; bespoke > generic |
Table 1: Evolution of AI Agents in Software Engineering. Caption: Tracking Masad’s benchmarks against real-world leaps shows exponential gains—each jump slashes human toil by 2-3x, per Replit’s infrastructure bets. Source: Adapted from talk transcript and SWE-Bench leaderboards.
This table isn’t just data; it’s a timeline of triumph. Spot the hockey stick? That’s the “test-time compute” hype Masad nods to—models like o1 or DeepSeek R1 gobbling tokens for smarter reasoning, now amplified by 2025’s GPT-5.
Trends, Twists, and Tidal Waves: Unpacking the Implications
Masad’s narrative arcs like a tech epic: From mainframes (expert-only fortresses) to PCs (Excel’s killer app birthing the world economy), software now flips from elite craft to populist power. Trend 1: Democratization. Unix in the ’70s demanded 6-9 years of training; today, Replit’s sandbox lets non-coders deploy via prompts. Anomaly? Early agents flopped on “habitat”—lacking cloud VMs, databases, or auth. Replit’s fix: One-line OAuth toggles, atomic file snapshots for reversible edits. Result? Agents fork environments, simulate fixes in parallel, boosting reliability 2-3x.
Trend 2: Autonomy Avalanche. Masad’s pillars for V3—end-to-end testing (via “computer use” like OpenAI’s Operator), sampling/simulations (hypothesis-testing forks), and auto-generated tests—tackle drift. Compare to Karpathy’s quip: Coding’s easy; the unsolved bits (deployments, payments) are Replit’s secret sauce. By 2025, Blitzy’s Verified leaderboard topper hints at orchestration layers emerging, where agents hire agents or humans for CAPTCHA. Human impact? Exponential leverage—one PM spins 1,000 agents for 95% success, turning solos into symphonies.
But anomalies lurk. Model collapse risk: Emma’s Q&A zinger—agents training on agent-code breeds “exploding error.” Masad’s counter? AlphaZero-style RL: LLMs self-play in sandboxes, not scraping human scraps. Globally, this spells upward mobility. Echoing The Sovereign Individual (1997 predictions nailing crypto/remote work), ideas trump capital. Satoshi’s solo trillion-dollar Bitcoin? The new normal. A Jakarta dreamer prompts Replit: “Build a micro-lending app for farmers”—boom, sovereign wealth from a laptop.
Trend 3: Economic Earthquake. SaaS dinosaurs? Doomed. Generic tools (HR, CRM) get custom-cloned for pennies. Businesses morph: Hierarchies flatten to networks, like open-source hives. Replit’s org? Generalist “product teams” blending PMs, devs, designers—one human, infinite agents. Implications? Less specialization since the Industrial Revolution. HR pros code; marketers agent-optimize. For emerging markets, it’s rocket fuel—bypass Big Tech gatekeepers, reward merit anywhere. Downside? Fragmented agents (Chinat’s worry)—data silos across lawyer-bots or sales-droids. Solution? Emergent protocols, beyond MCP’s RPC limits.
Visualize the shift:
To craft this simple line chart, I simulated SWE-Bench’s ascent using Python (via a REPL environment). X-axis: Years. Y-axis: Score (%). The curve? A classic exponential, from futile fiddles to frontier feats.
Figure 1: SWE-Bench Score Trajectory (2022-2025). Caption: Masad’s “outdated” 70-80% call was prescient; actual 65% in 2025 underscores the trend. Each tick? A step toward zero-touch software, empowering global creators to outpace incumbents.
Anomalies? Overhype in crowded niches (SDR agents galore), per Sophia’s query. Masad’s advice: Lean on domain passion—build compliance bots if that’s your jam. For job-hunters (like the Q&A seeker), join early-stage startups: Employee #20 at Series B > FAANG drone. Mindset hack: Swap to-do lists for missions—”Make the company win.”
The Sovereign Dawn: Key Takeaways for an Agent-Powered World
Masad’s talk isn’t a forecast; it’s a flare gun for the intelligence age. We’ve journeyed from mainframe priests to PC populists; now, agents usher sovereign creators. Bold prediction validated: Software’s app layer hits zero, but platforms like Replit thrive as “universal problem solvers”—managing your quantified self, procuring wearables, even agent-hiring wallets.
Key takeaways, bullet-sharp:
- Empower the Generalist: Jobs unsilo—seek startups where you’re a PM-dev-designer hybrid. Global twist: Merit anywhere; a clear thinker in Lagos rivals Palo Alto.
- Bet on Habitat Over Hype: Agents need sandboxes, not shackles. Replit’s transactional OS? The unsung hero pushing 65% SWE-Bench to 95% autonomy.
- Ideas = Infinite Wealth: Test hypotheses at light-speed. Sovereign individuals assemble/unwind teams (human + agent) like Uber rides—transaction costs nil.
- Guard the Human Spark: AI excels at recombination, not raw novelty. Lawyers in rare cases? Irreplaceable. Education pivot: Liberal arts + STEM for broad-world engineers.
