I sometimes wonder what the alternate reality where semiconductor advances ended in the eighties would look like. We might have had to manage with just a few MB of RAM and efficient ARM cores running at maybe 30 MHz or so. Would we still get web browsers? How about the rest of the digital transformation? One thing I do know for sure. LLMs would have been impossible.

Well, we wouldn't have ads and tracking.

I don't think there's really a credible alternate reality where Moore's law just stops like that when it was in full swing.

The ones that "could have happened" IMO are the transistor never being invented, or even mechanical computers becoming much more popular much earlier (there's a book about this alternate reality, The Difference Engine).

I don't think transistors being invented was that certain to happen, we could've got better vacuum tubes, or maybe something else.

And imagine if telecom had topped out around ISDN somewhere, with perhaps OC-3 (155Mbps) for the bleeding-fastest network core links. We'd probably get MP3 but not video to any great or compelling degree. Mostly-text web, perhaps more gopher-like. Client-side stuff would have to be very compact, I wonder if NAPLPS would've taken off. Screen reader software would probably love that timeline.

you are wrong. Windows 3.11 era used CPUs with like 33mhz cpu, and yet we had TONS of graphical applications. Including web browsers, Photoshop, CAD, Excel and instant messangers

Only thing that killed web for old computers is JAVASCRIPT.

When MC68030 (1986) was introduced, I remember reading how computers probably won't get much faster, because PCB signal integrity would not allow further improvements.

People that time were not actually sure how long the improvements would go on.

We did have web browsers, I had Internet Explorer on Windows 3.1, 33mhz 8mb RAM.

I remember using the web on 25mhz computers. It ran about as fast as it does today with a couple ghz. Our internet was a lot slower than as well.

Stunning work! Astounding progress since its under 3 months old from PCB to this result.

Funnily enough I've been musing this past month would I better separate work if I had a limited Amiga A1200 PC for anything other than work! This would nicely fit.

Please do submit to HackaDay I'm sure they'd salivate over this and it's amazing when you have the creator in the comments. Even if just to explain no a 555 wouldn't quite achieve the same result. No not even a 556...
