Except you and me don’t have the specific knowledge of the firmware in the upcoming M2 or M3 chip due out in 2024.Let them. Then they'll just go hire more talented people. Plenty of them out there who would be so grateful to have a job at Apple. Me included.
Remember, these aren’t Walmart cashiers they’re replacing. In some instances, there’s maybe a handful of human beings who can even do the job and replacing them is a nightmare, and extremely expensive. There’s no training or documentation to teach the new guy, it’s coming from the current guy’s Albert Einstein like brain — and you better believe it’s a problem for Apple if he or she takes that proprietary knowledge to Google or Microsoft or plenty of other shops.
There’s relatively few people who aren’t replaceable in the business world, but Apple has more than virtually any other company.
