I am sad to see WindowsNT, Linux and macOS be the only dominant operating systems.
My personal very perhaps unpopular view is that Windows NT has a better technial implentation than Linux.
Linux does most things well, form small devices to big iron. That is true now.
But when it started, it was as a learning experiment, and damn good one too. An amazing achievement. A lot of work my haorsd of people have since built on top of it, replaced things, epanded things, hardening things, adding drivers, etc. And it has come a long way, but to me as an operating system, technically it is not that inspiring.
I wish we had maybe 10 competitve opearing systems, some brand new off the presses.
I have run Linux in one form or another since the first Yggdrasil release at the end of 1992. (not very early).
It was amazing. Running it on my PC at home and it was faster than the terminals at school (well all shared a few servers so always a lot going on, I am sure if you had it all to yourself it would be faster. I guess that is why some people spent the nights there is they had demanding tasks to run, but htye were not a priority to get access to the better, newer and a lot more dedicated hardware. (It was a complicated process).
I could do 90% of what was needed at home, woot.
I was very happy when I get my paws on the first WindowsNT release back in 1994 I think. I had preordered it.
I cold not wait to install it.
processor-independent, multiprocessing and multi-user operating system the end of 1992.
After having suffered through the pain that was Widows that had a kinda sorts maybe a little multitasking. Finally an improvement. OF course, a lot of my software refused to run on it, or it refused to run it
The first Mac I had with macOS was also very cool, since then OpenBSD, I had NextStep when they released it for Intel. Very cool.
Anyways I have been waiting since to get a new operating system that levels up the game, as much as WindowsNT did for Windows 3.11, 95, 98, me.
I have not yet had that privilege.
I had good hopes for Plan9, QNX, a reimplementation fo BeOS that is still ongoing. (I might have the wrong name on that one. I remember a demo I had at the university of a BeBox with the BeOs and how well it multitasked what backed then seemed like very CPU intensive graphics manipulation while playing a video and some other stuff -at the time-... I never got a BeBox and havent run its OS)
There have been, and are some solid research OSs but they have never made it out into the real world.
WindowsNT, Linux and macOS cannot be all we are given. What replaces them?
Where is WindowsNTNT.
Will it take quantum computers to become the norm before we get it? Maybe Linux already runs on that too.
(if quantum computers ever become viable or even a good fit for everyday boring computer stuff).
Give me a new operating system, written from scratch, to implement every secure feature it should have, harden it, eliminate even the possibility of buffer overflows and assorted tasks, or create them so that the elements that are exposed can fail gracefully and non-destructbily and not leak data or allow inputting of data.
I forgot about Qubes OS, that is very interesting. Maybe that is it.
