Based on what? Hopium? Open source maintainers are burning out and even extremely popular projects struggle to recruit new devs to help. What's supporting your argument here besides "lol idk they'll figure it out I guess"
There's a ton of load bearing stuff that's going to break once maybe 100 people have enough and stop thanklessly maintaining things. In fact it's even worse than being thanklessly expected to fix shit since people are outright hostile towards you for maintaining your own passion project that nobody else wants to help with. And now you have people pushing AI slop PRs they shat out of Claude in 15 seconds, and you're expected to comb through it and suggest changes?
And don't even get me started on AI's ability to code. It can work well for small constrained tasks like scripting or unit testing. It breaks down entirely when you aks it to maintain a complex code base for years. It just can't help but duplicate code, delete features, spam files, and it has no ability to architect a project.
