No matter how good AI gets, how will a vibe coder maintain the code base? Or keep it up to date with the latest software it works with?

If it gets to the point where a vibe coder can ask for the ai to update the code for him and it works perfectly, then I can guarantee the vibe coder will lose access to the AI. Capitalism will step in and the rich will keep it exclusive so they can turn a profit with entirely ai run companies selling ai made digital products and software.

It's already happening to an extent. To get any real use out of it you have to pay to use it. Grok went from limited free use and unlimited paid, to extremely minimal free use and limited the paid tier to the extent of the old free tier, made a higher paid tier and limited that too. As soon as exclusive licencing deals with big corpos start happening, regular people using it effectively will be a thing of the past. Except as an ad platform of course.
