I recently saw a comment chain about nuclear bombs, and that led me to thinking about this. Say there is a nuclear explosion in the downtown of my US city. I survive relatively fine, but obviously the main part of the city has been destroyed, while major zones extending from the center were also badly damaged. What would be a good response to (a) survive and (b) help out the recovery effort?
The longest stretch would likely be chip fabs. You need precision electronics and hazardous chemicals and plenty of power.
But considering that some form of electronics will survive, and it wouldnt take long for people to get rudimentary electricity going, I don’t see why we couldn’t have world Internet within a decade.
Yeah, chip fabs are exactly why I think computers would need more time. I’m not super familiar with this, but I’d wager such a factory can only be built using tools and machines that come from other specialized factories, and so on maybe 3 levels down before you get to a relatively rudimentary manufacturing process that can be reasonably achieved within a few years. It would take a lot to get that back up and running.
By the time nuclear war happens, most chip manufacturing capability will be underground or in hidden sites and therefore not targeted.
How could you be sure of any of that? For all we know, nuclear war could start tomorrow. Or, a bit more realistically, next year. How fast can these factories be built?
However… Just think about how many chips are currently just sitting around… Between scrapping and searching you would likely be just fine for a few decades.
EMP would fry most of them though.
Only if they were currently running, and I’m willing to guess the vast majority of reusable/scrap chips will be unpowered in the event of an EMP.
Replacing all working electronics with new boards would definitely be a task. But unless we get an massive flare from the sun I hardly think that’ll be an issue.
