I think this will follow a typical business cycle. When the next recession comes, investors and companies will focus on shorter term ROI, and many high end developers and long term projects will seem too expensive. Reduced competition will dramatically affect the top end, and non-salary benefits may drop quite a bit. The median salary will probably remain sticky but lose a bit when adjusted for inflation. Eventually the next expansion starts but it may take a very long time for the top end competition to heat up to this degree again.
I don't expect low-code, AI, or developer productivity jumps to have any real impact anytime soon; there's no real evidence of a true jump in the productivity of the overall project.
