i'm 24. I think that improvements in tech nowadays mostly involve the hobbyist of any niche, while the general public is ever more satisfied with what already exists.
sd to hd to full hd was cool, full hd to 1440p i can see the difference, at 4k yes but it is not so big. Miniled is something people won't really care about imho (and they can already go very bright, i'm only waiting for more minileds to be integrated in monitors before changing mine).
Audio, well, most people will be satisfied with cheap razer/gaming/bose/whatever headphones are there. Sure anc is cool if you're in a noisy environment quite often
Bikes, well at 24yo i'm not really knowledgeable to say whether a bianchi that costs more than a motorbike is worth the upgrade from an older model... but ebikes are kinda nice even for people outside of the cycling world
However, what has happened with audio and video - and a change that i can perceive -, is the prices of things (not cpu/gpu related, for obvious reasons) coming down. oleds were so espensive ten years ago, now they are not. 4k minileds monitor are as expensive now as my regular non miniled 1440p va monitor from ~4/5 years ago. Hifiman has (permanently) slashed the prices of its headphones more than once over the years. It is not exciting as new tech but it is "just" nice
p.s. wifi printers are a pain in the ass much more than cable printes, and for llms i am kinda happy with them, i'll give you that, they're a godsend for studying; i'm less excited about the idea they'll replace most workers
