My perspective is that each year a good chunk of senior dev leave the pure dev to go to management roles or something else and while they do that, they are replaced by junior morphing into senior. I consider 8 years to be the real experience to be considered a senior dev. If from now on, the amount of junior is drastically reduced, this will lead to a lack of senior in 8 years because the senior leaving should be the same proportion. In a situation where they replace juniors with agents, yes, we'll still be senior, but just like people capable of setting a VHS recorder, our number will dwindle.
