How can we advance in the future if we keep clinging to the past?

Well we certainly can't advance in the present if we scrap everthing we already have and start over. In which case, somebody like you would just complain in another 50 years.

How about we gradually start moving to something better already?

Define better. What would it look like? Is our current state "better" than it was in the past? Is there reason to believe the future state will be better or worse than the current state?

IBM created the System/38 in 1979, and it was still more advanced than even research OSes like Singularity and EROS today, but legacy support for the System/360 and System/34 kept it from becoming IBM's main computer. It had 128-bit capability-based addressing with strongly-typed protected pointers. Paging, multi-tasking, and dynamic linking were part of the hardware and microcode. Even the microcode was multi-threaded. Running a program and calling a dynamically linked function were the same. It had generalized queues for IPC, user I/O messages, I/O devices, and user storage. Communication between microcode modules, I/O processors, running processes, suspended processes, other System/38s, and users was done in the exact same manner. Variables were late-bound and dynamically typed at the Machine Interface level, so with a single instruction you could add e.g. packed decimal and binary, and store the result in a floating point number even if you didn't know the types of these objects when the program was compiled. There is no distinction between objects in RAM and objects on disk, so programs and other read-only data could be discarded and re-read from the original copy on disk instead of swapping. It was designed for a transition to bubble memory or other non-volatile storage so they made all data on the disks addressable by virtual addresses and had the microcode and I/O processors provide a single-level store with a single address space.

Even the microcode was multi-threaded.
Sounds like a unicorn to me.

Yes but will it blend?

The CPU is multi-tasking by design and has a scheduler in hardware. The microcode is made up of independent modules that run as separate threads. Each module has a wait queue and is activated when an appropriate message is placed on the queue.

So, programs and their outputs were just functions returning values? This is exactly how it should be, and isn't today.

I'm grateful for letting me know about System/38, >>6-san.
