Why it matters
AI applied to development moved the bottleneck. Writing code stopped being the slow part; now the slow part is reviewing, understanding and maintaining what was written. Any team adopting these tools without adjusting review gets faster in week one and slower by month three.
I look at it from operations, not from the demo. The question is not whether the assistant writes a correct function, but whether the team can maintain what it produced six months later, with different people, without the original context. That is the real test and it almost never appears in the announcements.
What usually goes wrong
The problem appears when somebody accepts code they do not fully understand but which passes the tests. It works, it ships, and six months later it needs changing. That is when you discover nobody on the team can explain why it is written that way, and the small change becomes a rewrite.
What to watch
- What happens to code review: if the assistant produces more, somebody has to read more.
- What happens to tests — generating code without generating tests only moves the problem forward.
- Where the source code travels when the assistant is used, and what the contract says about it.
How I read this entry
I would treat it as a process change, not a tool change. The assistant shifts who does what inside the team, and that has to be discussed with people beforehand, not discovered in the retrospective once somebody already felt replaced.
