Have you met programmers? Even those who care about quality are often under a lot of pressure to produce. Things slip through. Before, it was verbatim copies from Stack Overflow. Now it'll be using Copilot code as-is.
Copilot is definitely no replacement for anything except copying from Stack Overflow for juniors.
But in the long run, AI is us basically us creating our own replacement. As a species. We don't realize it yet. It'll be really funny in retrospective. Too bad I probably won't be alive to see it.
