"AI Will Kill SaaS" "SIers Are Done" — Fact or Fiction? (Article Analysis)
Article Overview
Source: ITmedia NEWS (via Yahoo! News Japan)
Author: Go Hisamatsu (CEO, Engineering Management Inc.)
Published: February 10, 2026
"Roles AI Cannot Replace" According to the Article
The article lists three reasons why "SaaS and SIers won't die easily":
| # | Role | Description |
|---|---|---|
| 1 | Accountability | Responsibility for explaining failures and legal issues. AI can perform tasks but cannot bear responsibility |
| 2 | Requirements Definition & Design | Personnel who determine "what to build" and "where the risks lie." Decision-making in ambiguous domains |
| 3 | Domain Knowledge & Regulatory Compliance | Expertise in accounting, labor, and legal matters, keeping up with frequent regulatory changes and understanding "what constitutes risk" |
Additionally, audit response (process explainability, evidence management) is mentioned as an important role.
Verifying Consistency Between Title and Argument
Issue: The AI vs SaaS/SIer Framing is Misleading
The title frames the discussion as examining claims that "AI will kill SaaS" and "SIers are finished," but the core argument is actually about "roles humans cannot be replaced in," not "roles AI cannot replace."
| Article's Claim | Actual Axis of Comparison |
|---|---|
| AI cannot bear responsibility | AI vs Humans (accountability) |
| AI cannot define requirements | AI vs Humans (judgment/decision-making) |
| AI cannot possess domain knowledge | AI vs Experts (regulatory understanding) |
Problems with the Logical Structure
Title's claim: AI → Replaces SaaS/SIers
Article's rebuttal: AI → Cannot replace humans
∴ SaaS/SIers are necessary
However, this syllogism contains a hidden premise:
"SaaS/SIers = entities that provide accountability, requirements definition, and domain knowledge"
If this premise is correct, the article's argument holds. But the following counterarguments are possible:
- In-house development: If companies hire their own accountability holders, requirements specialists, and domain experts, SaaS/SIers become unnecessary
- AI + Human hybrid: A division of labor where humans handle responsibility and judgment while AI handles implementation
- Definition of SaaS/SIers: The article defines them as "mechanisms for externalizing knowledge and responsibility," but this doesn't necessarily mean current SaaS/SIer companies
The Article's Implicit Conclusion
What the article is actually arguing:
"Entities with accountability, requirements definition capability, and domain knowledge" are necessary—and if a company doesn't have them in-house, it must rely on external providers (SaaS/SIers)
In other words, what "AI cannot replace" is not precisely SaaS/SIers themselves, but rather the "human expertise" that they provide.
Verification Results
| Aspect | Assessment |
|---|---|
| Title sensationalism | High ("kill," "done" are clickbait) |
| Logical soundness | Medium (argument holds if premises are made explicit) |
| Validity of conclusion | High ("entities with explainability are necessary" is correct) |
| Title-argument consistency | Somewhat low (not AI vs SaaS/SIer, but AI vs human expertise) |
Conclusion
The article's argument itself is valid, but the framing suggested by the title—"AI will replace SaaS/SIers"—does not accurately reflect the content. A more accurate title would be:
"Will AI Make 'Expert Personnel' Obsolete? Three Limitations Shown by Accountability, Requirements Definition, and Domain Knowledge"
Whether SaaS/SIers survive depends not on AI capabilities, but on whether these companies can continue to function as "accountable entities with explainability."
Why This Matters Now: The Claude Cowork Moment
In February 2026, stock markets reacted sharply to Anthropic's Claude Cowork release. Why the sudden panic when this debate has been ongoing since 2024?
Claude Cowork represents a turning point, not just another tool:
| Before Cowork | After Cowork |
|---|---|
| AI as "assistant" — suggests, helps | AI as "agent" — executes, reports results |
| Human orchestrates multiple tools | AI orchestrates tools autonomously |
| "AI might replace X" (theoretical) | "AI is replacing X" (demonstrated) |
The market's reaction wasn't about Cowork's capabilities per se—it was the proof of concept that shifted "AI disruption" from speculation to inevitability.
Key insight: Claude Cowork is a brilliant day laborer—it has no memory. Each session starts fresh. In contrast, AI assistants with persistent memory (like Gaia on PinotWalk) can maintain context across conversations, enabling complex multi-step analysis like this article.
Global Perspectives: The Deterministic vs Probabilistic Framework
The most influential framework emerging from this debate divides software into two categories:
Deterministic Systems (Will Survive)
- Characteristics: Requires 100% accuracy, audit trails, legal compliance
- Examples: Financial ledgers, medical records, regulatory filings
- Why AI can't replace: Not because AI lacks capability, but because legal liability requires a responsible entity
Probabilistic Systems (Will Be Disrupted)
- Characteristics: 80-95% accuracy is acceptable, speed matters more than perfection
- Examples: Draft generation, data analysis, code scaffolding
- Why AI will dominate: Faster, cheaper, good enough
This framework suggests half of SaaS will die, half will be supercharged — the question is which half your product falls into.
The Real Question: What Can't AI Replace?
After synthesizing global perspectives, one answer emerges:
Not expertise. Not judgment. Not even "accountability" in the abstract sense.
The only thing AI truly cannot replace is legal personhood:
- Signing contracts requires a legal entity
- Bearing liability requires someone who can be sued
- Regulatory accountability requires a registered business
AI can draft the contract. AI can assess the risk. AI can ensure compliance. But AI cannot be the responsible party.
This is why SaaS and SIers won't simply "die"—but they will transform. The value proposition shifts from "we have expertise" to "we bear responsibility."
The Real Question: What Can't AI Replace?
After analyzing multiple perspectives, the consensus narrows to one irreducible element:
Legal personhood — the capacity to sign contracts, bear liability, and face consequences
Everything else — requirements definition, domain expertise, regulatory interpretation — is information processing. And information processing is precisely what AI excels at.
The article's original argument ("accountability, requirements definition, domain knowledge") conflates two distinct things:
- Information processing (AI can do this, often better)
- Legal responsibility (requires natural or legal persons)
SaaS and SIers survive not because humans are better at thinking, but because someone must be accountable when things go wrong.

The Critical Difference: Persistent Memory
| Capability | Claude Cowork | PinotWalk Gaia |
|---|---|---|
| Session memory | ❌ Resets | ✅ Persistent |
| Document history | ❌ None | ✅ Full context |
| Knowledge accumulation | ❌ Starts fresh | ✅ Builds over time |
This article exists because Gaia recalled the original Japanese text, translations, research, and edits—all in one flow.
My Personal Opinion
The following points claimed as "irreplaceable by AI" can actually be handled by AI:
- Requirements definition
- Domain knowledge
- Regulatory compliance
The only things truly irreplaceable by AI are those inherent to being a natural person or legal entity. Information processing should be considered replaceable by AI.
