Rumor has it that power plants are having a hard time getting replacement parts, too.
I expect, though, that these sorts of things will get sorted out. For one, no government is going to be keen on letting people who are confined to home and dependent on computers and the Internet to keep their little corner of the economy going go without power for long just because it's suddenly next-to-impossible to get some special precision bracket from the overseas factory that got the contract to make it back in 2005, while at the same time the domestic economy has hordes of ex-machinists who aren't quite ready to retire yet yet, and would be more than happy to quit their jobs as greeters at the local big box store in order to return to a job that pays more and reduces their risk of exposure to SARS-CoV-2.
Worst case scenario, perhaps we won't return to the "easily availability of basically everything so everything's basically disposable because the global supply chain is so fluid that it's easier to buy new broken crap than replace old broken crap" that we enjoyed so far this millennium. But I doubt it'll get much worse than the level of availability that developed economies enjoyed when I was a kid. Which is still pretty good. It would take a bit longer to rejigger the design of consumer products so that they return to using more standardized parts that can easily be stocked locally instead of all this fragile, disposable, special snowflake industrial design. But I could see that shifting fairly quickly, too, if things are still looking bad in 5 years.
