But it's not 1970 and most of the stuff that's critical for the proper functioning of the industry and society and everything else at least in some way relies on computers and electronics, and the stuff that isn't is for the large part long scrapped. Like, imagine all the fancy cnc machining centers are bricked, what are you going to replace them with? You can't say "just machine it manually lol" because there's simply not enough manual machines or skilled people to operate them, and you can't build new ones because there's no existing industry to do it that isn't crippled by lack of electronics as well, and the parts they need to make were designed with cnc capabilities in mind in the first place and might be really awkward to make manually.
Of course people will pick it back up eventually, but it will require lots of resources and concerted efforts, and if electronics is gone overnight it won't be 1970, it will be stone age, even if for a brief period, but with a population and infrastructure that can't be sustained with stone age methods. This will lead to a massive famine and war before anything else could happen. Nobody would have time to spare a thought about industrial manufacturing between having nothing to eat and fighting off armed gangs who's after whatever little scraps you've left.
In any case, this is of course a purely hypothetical scenario because a flare powerful enough to actually destroy electronics worldwide is also likely to just directly damage the planet's environment and make it inhospitable to life anyways.
