So far for most organizations and services other than the ones I mentioned reliability has been the same this year as it was before. So I call that "working just fine".
How many major companies are pushing unreviewed code to prod? Seems like mostly an early stage startup thing and their bugs and outages aren’t going to make the news. I’m skeptical that even a majority of Anthropic and GitHub’s code new code this year was unreviewed.
Claude Code is entirely vibe coded and while earlier this year you could see the vibe coding leaking though lately that’s been much less the case.
