The Byte era was very much "extremely wealthy values of anyone."
The original 16K Apple II cost the equivalent of more than $5k. If you wanted 48k - and you did for any kind of non-trivial programming - the equivalent price would be $11k.
Computing isn't dead, it's just entirely commoditised. Most people who drive cars don't care about what's under the hood. They don't care they could build themselves a custom engine which is four times as powerful. They just want a transport appliance that works reliably and doesn't cost too much to run.
Modern phone-based computing is actually an insane success. Go to a restaurant and you'll get a QR code link to today's menu, which can be changed daily or even hourly. Sometimes you can even order from the table.
Go to a show, book a flight, or maybe just use some public transport, and there's a good chance you'll be able to use a digital ticket. Or at least use your phone for payment.
You can book medical appointments, fill prescriptions, track your fitness, and so on - all with one device.
Never mind basics like location and navigation, which aren't even surprising any more. If you ever use a paper street atlas you'll see how convenient they are.
The fact that you can't write your own code is of zero interest to most users. They don't want to write their own code. They just want something that makes life simpler. And mobile computing does.
The real problem are the social media monopolies and ad tech. But those are a political problem, not a technical one - specifically regulatory capture which neutered the anti-trust laws and allowed most commodity computing to be owned by a handful of monopolies.
