And on some level, this makes sense. A completely junior employee may well need substantial guidance, and if they aren't reliable that won't necessarily be easy to predict - so you get them a supervisor who can evaluate their work in full. A midlevel or upper-level manager ought to be competent enough to perform reliably, and it's more useful to have someone above them with skills they don't have.
(Of course, hiring is a mess, and "senior staff ought to be qualified and reliable" is not the same as "senior staff are...")
In 4 levels of management the CEO is not to be the BS detector of the 1st level but most def. be "technical" enough to detect B.S. at the 4th and (maybe) the 3rd levels of management.
Those I admire and have studied: Disney, Elon, and Jobs (many others) could maybe detect down to the 2nd and 3rd levels. To do the impossible - you must have a grasp of the "possible"
There's a natural (and I think fundamental) inversion that happens as you go up the leadership chain. The first level of supervision almost inevitably knows more than the most junior employee about their area of work. (Think a senior developer mentoring a new college hire.)
That may hold for two levels, but at some point, management is about breadth and not depth. The head of technical operations probably came from networking or systems or storage or database or communications, but probably didn't come from ALL of those, so is unlikely to know more about networking than the head of networking AND more about databases than the head of databases, etc. In fact, they may know next to nothing about some particular field of ops and yet still be the right choice to lead operations. (I was in this position in a prior role.)
So you get this weird situation where at the junior levels, the supervisor knows more than the supervised. At the more senior levels, that's usually inverted. And then you get people who determine that the senior person is clueless because they know more about their specialized field than the boss.
IMO, it's unreasonable to expect the CEO of Boeing to be an expert in finance, operations, aerodynamics, manufacturing, supply chain, engine design, certification rules, avionics, landing gear, radar, flight controls, and the 100 other disciplines needed to make Boeing work. I see no reason to think that technology is extra-special in that all managers of technologists need to be world-class technologists.
