Computers have become so stagnant it's disgusting. If I compare my 1987 Amiga (with some slightly newer parts and software ;-)) with a computer that is 19 years newer, there seems to be only minor improvements and even some things that are WORSE. Here are some things I thought we'd have before 2000:
1. Ultra high res displays and the end of anti-aliasing
It seems these days higher resolution just means bigger displays, but back in 1998 I read an article about IBM prototype displays with 10x the resolution density. Their prototype was 17" but resolution was something like 22,000 x 9,000. This would make anti-aliasing a thing of the past because everything would be as crisp as print on paper. I think they said something about Windows having to support this and that may explain why we'll never have it.
2. The death of Virtual Memory
With 64bit processors and the ability to access >4Gb of RAM, why do we still have slow annoying virtual memory? Virtual memory should have been a temporary workaround until memory became plentiful. Why swap back and forth, shortening harddrive life and slowing everything down (and causing major problems if you don't "shut down" properly).
3. The death of optical discs
In 1997 I read about holigraphic storage cubes which could contain much more data than DVD, required no spin-up time (non-moving), were cheap to produce and were the size of a sugar cube.
I've always loved Compact Discs for music, but hated it in computers (slow spin-up, stupid inactivity spin-down). DVD - which I waited for since 1990 - turned out to be crap (like a VCR with Windows on it, crashing all the time).
4. 3D OS
They've talked about this since the '80's. I've seen 3D OS demos (in the late 90's) with hundreds of floating windows (in 3D, obviously) and flipping looked easy. Switching multiple applications using standard desktop is a pain in the arse (at least Amiga has multiple screens).
5. Speech recognition
Whatever happened to that? I'm not saying I want to type a document by saying it, but it might be good for fast OS access like switching windows, running automated tasks or opening programs. Maybe we've already got this, but I haven't seen it.
6. The death of Windows
Just kidding - but this would actually be a computer advance ;-)
Anybody have anything they've been waiting for?
