I don’t think that’s true. There are developments that really do constitute genuine progress: for example, going from CRTs to LCDs. It’s hard to imagine a world populated by high-resolution, energy-efficient, colour-accurate flatscreens suddenly being replaced by the invention of a gigantic ugly box that performs worse on every available metric.
…and yet CRTs still exist as a ‘niche’ product. There’s a whole corner of the internet where people admire and collect them.
It may well be that ‘spatial computing’ or whatever you wish to call it is going to be a genuine step forward, but it’s also easy to imagine it might not be. And that’s not true for every technology.
Except motion. In which twenty year old monitors on my desk make everything put next to it look abysmal by comparison.
