These comparisons are fun at all but a better one would be the difference between whatever "computer" a citizen lambda would have used back in the day and the cray1 and whatever on can use now and the current "cray" (or whatever humans use now) and see the difference of cost.

The first Cray-1 was installed at Los Alamos National Laboratory in 1976. That same year Gary Kildall created CP/M and Steve Wozniak completed the Apple-1.

Cray1 should be compared to nowadays raspberry pi pico 2 / rp2350 which has similar specs (using external ram).

I won't rest until the average microcontroller in an optical mouse is more powerful than a Cray 1.

I'm not aware of any optical mouse using a general purpose MCU, to my knowledge they are all using ASICs

Hardware has gone a long way...

...software... well, that's a different story.

While a cray could compute millions of things and did a bunch of usable stuff for many groups of people who used it back then, a raspberrypi today has trouble even properly displaying a weather forecast at "acceptable speeds", because modern software has become very bloated, and that includes weather forecast sites that somehow have to include autoplaying video, usually an ad.

What happened to the programs/problems the Cray 1 solved? If anyone can do it on commodity hardware - is it being done? Is it all solved?

Work in computational fluid dynamics is limited by computing power. Bigger and faster computers give more accuracy and speed.

A “famous” instance was the use of a Cray to render the collapse of Jupiter in the movie “2010”. A very early example of CGI in cinema.

Some gaming mice do for running RGB lights, macros, or whatever.

> but then again if you'd showed me an RPi5 back in 1977 I would have said "nah, impossible" so who knows? I was reading lots of scifi in 1977, so I may have tried to talk to the pi like Scotty trying to talk to the mouse in Star Trek IV. And since you can run an LLM and text to speech on an RPi5, it might have answered.

Someday real soon, kids being shown episodes of 'Knight Rider' by their grandparents won't understand why a talking car was so futuristic.

Like James Bond's Aston Martin with a satnav/tracking device in 1964's Goldfinger. Kids would know what that was but they might not understand why Bond had to continually shift some sort of stick to change the car's gear.

No. With more computing power the level of detail increased.

And some problems are even more complex.

My father spent his career on researching coil forms for Stellerator fusion reactors. Finding the shapes for their experiments then was a huge computational problem using then-state of the art machines (incl. cray for a while) and even today's computing power isn't there, yet.

Other problems we now solve regularly on our phones ...

The self driving aspect, amazingly, is already here and considered mundane.
