It's becoming widespread in all industries, for example, nearby factory had to cut down the production of their household appliances because suppliers can't supply enough digital indicators, now they are doing a crash program to make old school analogue one and discovered that despite still making them less than a decade ago, it's basically a lost art to them.
A big factor in current decline is not just over reliance on overseas suppliers, but also taking infrastructure and knowledge base among domestic supplier for granted and thus skimping on their maintenance, all in the name of big line going up in the quarterly reports to the shareholders. people with critical industrial skills have been ''disappearing'' for years and the process entered the tipping point during the kung-flu closedowns, same with infrastructure as people found out the hard way that you can keep a rundown facility running by jury-rigging stuff, but once it is closed for some time, it's terribly hard to get it running again. I read few months ago about a factory making specialist industrial lubricants, burning down (underfunded maintenance), it cowered approximately half the needs in North America, there is no one to take up the slack and it is unlikely to be rebuilt, due to too low profit margins.
