Computers at that time were already pretty okay. Doom is from several years before this.
What you should instead be wondering is why so much stuff today fails to display even this level of interactivity.

I'm looking forward to the next decades, there's a demographic collapse on the horizon, global supply chain are weakening. The incentives to bring back manufacturing onshore will increase and that will require full understanding and will likely put constraints on supply anyway, just less so than a total collapse. Software will have to adapt and get all the compute results to a much better power efficiency.
