To a certain extent I agree. We have watched it happen to Hot Rods, Ham Radio, even woodworking to a lesser extent. If you focus on that last one, the future looks less "grim" for those that do not want full automation.
Hobby woodworking made HUGE leaps and bounds in technology from the 1950's to about the early 1990's. It did not stall at that point but the focus moved to just making the same equipment cheaper (planers, jointers, quality hybrid or small cabinet saws).
Innovation in automation has not really made any strides...part of it might be the footprint required but I think it has more to do with hitting a wall. At some point it became clear if we go any further, the hobby will not support it because the "hobby" goes away.
Home brewing will likely reach a crossroads where one camp focuses solely on recipe creation and inputs that into the Beermatic 2024 while the other camp focuses on having MORE involvement in every step of the process. Just look at how many folks bought and use the Pico/Grainfather/Braumeister/etc...then look at how much growing your own hops has increased in popularity.
