Let's replay this post but imagine Google made this announcement before LLMs were wide-spread (say, 2019). Below, I replace "AI" with "human programmers".

    > What remains to be seen is whether Google also introduced more Chrome bugs in June than over the past two years, thanks to human programmers.

    > The big problem is that human programmers output can be very convincing and look "right", even appear to work, until you examine it in detail and realise all the edge-cases it didn't handle.

Your argument falls apart quickly because the exact reverse is equally as likely. Also, whenever I see someone say "just wait longer" for some effect to become apparent, it feels like a lazy argument.
