Another thought this triggered for me, related to photo:
A lot of hobbies as they digitize have moved to having 0 OpEx but much higher CapEx.
Photography for example, bodies/lenses didn't change much for 10-20 years, and didn't cost that much. There was recurring expense for film/dev/prints that scaled with your usage, and arguably you could GAS out on those smaller purchases.
In the film era for reference, you had Nikon F 1959, F2 1971, F3 1980, F4 1988, F5 1996, F6 2004. The entire film era Nikon had 6 flagships in 45 years! You could use the same camera for 20 years and only be maybe 1~2 generations behind at the end! There just wasn't much to upgrade to.
With digital bodies cost a ton, and even as we've slowed advancement.. you still get a new flagship body every 3-4 years (down from as little as 2 years in the early Sony A7 days). Some is tech advancement but a lot of it is parcelling out improvements sparingly cycle by cycle to try to drive sales in our modern higher consumption era.
