Well worth ★★★★★.
I'm not sure that I can go with the *detail* of the story, perhaps because I'm not sure if the technology will be available "whenever" to, say, fabricate better fabricators -- though I'm sure scavenging would be a viable option -- or whether we'd have to reinvent the loo roll, the toothbrush, and dry stone walling. There is a helluva lot of necessary infrastructure behind even moderately-complex electronics these days, and if that was compromised, we may find the whole house of cards come tumbling down.
