Bain tests software takeover targets by vibecoding AI replicas

> any evidence of this.

"Any evidence" you say? I think something has moved.

As of Autumn/Winter 2025, I can say "Here's a complete enough spec of what I want cloned. Crank on it for a few hours. Give me the clone site as I specified." And frontier agentic tooling does a hands-off YOLO job really well. (Notice: I set it up with good specs/rules to scaffold.) Cost maybe an hour of my time to set up/scaffold, and 3 hours cranking on its own, on a $20 or $60/mo sub.

I think taking the same problem to an "offshore house" (or even Fiverr or whatever) would probably easily cost 10-100x more, and quite possibly with worse (less reusable or less best-practices code quality or less functional or less clean) output overall.

So I think your OVERALL point may stand. I'm just nitpicking the specific aspect quoted above, and maybe to some degree the aspect of

> "LLM generated code is similar, but arguably more expensive and lower quality"

Which to be fair obviously depends on what code one is comparing.

I used to say "nah, it can't replicate apps that well by itself", but then I tried it (on the advice of a fellow commenter here on HN), and was surprised myself.

If your argument is that LLMs are more effective and less costly than typical low-quality outsourced code, I generally agree with that, depending on the details.

For prototype/POC stuff, absolutely.

For long term deployable product stuff that needs to be maintained, supported with SLAs etc... eh, like everything, it depends on the people/team.

I've been leading dev teams for around 25 years, and I tend to think in terms of total cost of code.

Cognitive debt is a real thing. The cost of a developer that leaves the team, and the struggle to have someone take over their work is real.

With LLMs you have all this hidden cost, plus no "theory of mind", which makes the cognitive debt much worse.

Combine that with atrophied skills, subtle bugs, architecture facepalms, security issues, etc... and the total cost of LLM generated code is a lot higher than just a subscription price.

The more likely scenario is that they "consume" the output of designated offshore teams.
