Vintage cars might still have much of the same appeal because they have tended to become increasingly more complicated. Perhaps a stronger example would be antique books or furniture.
I agree, I love vintage cars because they're simple and impressive in an understandable way. I also prefer the feel, since it's more analog and connected to the road, and they often did more with less than modern cars, similar to how old computers were often more responsive with less. Cars need safety features and more complicated electronics, just like software needs security and telemetry/monetization now. And just like I'm impressed by modern CPUs and GPUs and SSDs and NNPs, I'm also impressed by modern turbo engines and things like skyactiv-x. I'd wager the reason people are always interested in vintage things is actually just that people are always interested in things. If we had access to future tech somehow, people would probably take interest in that as well
This is what I think. When a modern laptop or phone is old, except for a few avid collectors, it will be junk. An amiga has a completely different appeal and therefore becomes vintage.
But how do you know that? Who's to say that 35 years from now, someone won't have this exact same sentiment when comparing a (then vintage) iPhone 12 to whatever people will use in 30 years?
