> The Real Bottleneck: Time
Already a "no", the bottleneck is "drowning under your own slop". Ever noticed how fast agents seems to be able to do their work in the beginning of the project, but the larger it grows, it seems to get slower at doing good changes that doesn't break other things?
This is because you're missing the "engineering" part of software engineering, where someone has to think about the domain, design, tradeoffs and how something will be used, which requires good judgement and good wisdom regarding what is a suitable and good design considering what you want to do.
Lately (last year or so), more client jobs of mine have basically been "Hey, so we have this project that someone made with LLMs, they basically don't know how it works, but now we have a ton of users, could you redo it properly?", and in all cases, the applications have been built with zero engineering and with zero (human) regards to design and architecture.
I have no yet have any clients come to me and say "Hey, our current vibe-coders are all busy and don't have time, help us with X", it's always "We've built hairball X, rescue us please?", and that to me makes it pretty obvious what the biggest bottleneck with this sort of coding is.
Moving slower is usually faster long-term granted you think about the design, but obviously slower short-term, which makes it kind of counter-intuitive.
