I think the vision here is more likely to play out, if any were to. Not many fabs that can make modern chips, and the biggest one is under the business end of Chinese artillery so. Gotta make do with whatever we have even if new supply dries up.
Uh, wait, I've properly read your comment now.
Still, I miss a ZMachine interpreter for DuskOS. And networking. Gopher, IRC and email (among maybe some NNTP client) are a must.
I'm assuming you're talking about the internet, networked services, etc, because that's the only conceivable way a collapse could happen that quickly... except all modern infrastructure we rely on like that has backups and redundancy built in, and largely separated failure domains, so that such a failure would never be able to happen that quickly.
Which means we might be living in collapse now, we just don't know it yet. "The Long Emergency" as James Howard Kunstler put it.
When a professional prognosticator's prognostications continue to be falsified by actual events, year after endless year, at some point don't people stop listening to them?
Funnily enough - not whatsoever! And the benefits of this amazing fact are reaped by economists* the world over, year after year.
* And, to be fair, journalists, politicians, various flavours of youtuber, etc, etc.
Yet people still listen to Musk about when Tesla will have autonomous driving.
We really have no way to predict it. It is even likely to be different in different locales.
- Industrial food will gradually become extremely expensive and homesteading will become more popular. Crop failures and famines will be routine as food security and international trade wanes.
- Unemployment will soar with automation and overall decreased purchasing power.
- Crime and theft will soar as police decline (Austin TX is already understaffed by 300 officers and doesn't respond to property crimes until 48 hours later)
- Civil/national/world wars.
- 100M's of climate refugees migrating across and between continents. If you think scapegoating of "illegal" immigrants is bad now, just wait until all forms of hate in the forms of racism, xenophobia, and classism become turbocharged. Expect militarized borders guarded by killer robots.
In terms of computing, this means that any strategy looking at a before/after collapse framing is missing the entire interesting middle part - how do we transition from this high-tech to low-tech world over the course of decades. I seriously doubt it can happen by anticipating what computing we might need and just leapfrogging there.
