This is 100% correct. At most Fortune 500s, there are a handful of old white males who can rebuild core infrastructure in the event of a major outage. Beyond their tribal knowledge, most critical systems are black boxes that go down in flames if anyone else touches them. The Boomers in charge refuse to train new people in those areas because it's "legacy technology" and not some bleeding edge bullshit the Boomers were told about at sales conferences. The boomers refuse to hire based upon merit, so there's almost no new one who CAN learn those skills. Any who can learn take one look at the river of DEI bullshit rapidly destroying the industry, pull a van & stock options routine, and retire as 4chan pointed out. It's currently a race between IT losing the ability to maintain Boomer pension software and fiscal realities to see which stops the pension checks first. That's the only thing which will turn this DEI ship around.
