Because having more powerful tools is a different problem from using them well.
When GUI apps first made it easy for anyone to use 100 fonts and colors in a document, it did not make the quality of design go up. The tools became more powerful but the average quality of design went down because lots of people with less skill could suddenly participate.
Same issue here, two things are true at once. Models and agents are very powerful, and it makes it possible for less skilled or less conscientious developers to increase volume of low quality PRs.
