You're reminding me of when Sun was using the slogan "The Network is the Computer," and even put it on a T-Shirt or two. Most tech-types I knew chuckled a bit. Someone had a T-Shirt printed up saying "The Network is the Network. The Computer is the Computer. Sorry for the confusion."

But I think what they were trying to say was "in the future, the data you use will be spread out all over the network," which, yes, was an advanced concept in 1995. And I hope it was a business strategy to try to sidestep MSFT's desktop dominance (otherwise they were doing it by accident.) I think Sun did a great job of helping create a world where your desktop OS didn't matter that much (I use FreeBSD, Linux, Win10 and occasionally macOS on a daily basis.) But it seems to me Sun really missed the mobile revolution. In the late 2000s, we had a Sun guy come and try to pitch the latest SPARC CPUs for mobile designs. IIRC, they had great per/cycle power numbers, but were just CPUs (not SoCs) and it was hard to throttle them down to the point where you could get decent battery performance. Alas, so much great technology, now wasted.

A big problem was certainly that Linux on commodity boxes became an industry standard. In 2000 it was still seen by many corporations as hobbyist amateur system. But then Google & Co introduced them into the corporate world and for many use cases a Linux box for 1000 bucks would do the same as a 10000 bucks Sun server.
