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.
For me the interesting alternate reality is where CPUs got stuck in the 200-400mhz range for speed, but somehow continued to become more efficient.
It’s kind of the ideal combination in some ways. It’s fast enough to competently run a nice desktop GUI, but not so fast that you can get overly fancy with it. Eventually you’d end up OSes that look like highly refined versions of System 7.6/Mac OS 8 or Windows 2000, which sounds lovely.
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.
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.
There are web browsers for 8-bits today, and there were web browsers for e.g. Amiga's with 68000 CPU's from 1979 back in the day.
We did have web browsers, I had Internet Explorer on Windows 3.1, 33mhz 8mb RAM.
> Would we still get web browsers?
Yes, just that they would not run millions of lines of JavaScript for some social media tracking algorithm, newsletter signup, GDPR popup, newsletter popup, ad popup, etc. and you'd probably just be presented with the text only and at best a relevant static image or two. The web would be a place to get long-form information, sort of a massive e-book, not a battleground of corporations clamoring for 5 seconds of attention to make $0.05 off each of 500 million people's doom scrolling while on the toilet.
Web browsers existed back then, the web in the days of NCSA Mosaic was basically exactly the above
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.
Apart from transputers mentioned already, there’s https://greenarrays.com/home/documents/g144apps.php
Both the hardware and the forth software.
APIs in a B2B style would likely be much more prevalent, less advertising (yay!) and less money in the internet so more like the original internet I guess.
GUIs like https://en.wikipedia.org/wiki/SymbOS
And https://en.wikipedia.org/wiki/Newton_OS
Show that we could have had quality desktops and mobile devices
