I shouldn't have used the term "vibe-coded" as that's an extreme charicature. But I would argue in general heavy use of LLMs just does lead to sloppier code, and I think there's a general feel for that. Has AI use helped Microsoft make better software lately?

People live to benefit from AI for their own work, but are understandably uneasy about depending on code written by AI, even if it's (mostly) human reviewed. 2-3% more bugs may not seem like a big deal, but when you start building stacks of things these bugs bubble up and increase exponentially.
