It does not really matter as even though the models get updated, the new data was produced with the help of the older models, it is feeding on itself.

Just imagine how hard it would be to push a new programming language. No AI models would be able to generate code in that new language, or they would be extremely limited. This would make adoption much more difficult in a world where all developers use AI tooling extensively.

I believe this trend could create new opportunities also: as everyone uses AI tools to generate statistically average quality code, only those not using AI tools will be able to create true innovation.
