Have you ever EVER heard a 40 year old say 'I was a lot smarter back in my 20s'??? never... more likely they'll reminisce about the stupid things they got up to.
Your certainly not losing your intellectual abilities at 40 or 50, far from it.
40 and 50 year olds will just be moving on to the next stage of their career, using their collected experience to manage and pass on knowledge. Coding requires focus which is difficult to come by generally when you're older and juggling many responsibilities that you've created in your life up to this point like family, finances etc. You certainly don't become dumb.
All the attributes of big tech organisations you described could be applied to many other fields. When you're at the bottom (like a smart 20 year old) and have no control, it can be frustrating. You can rebel against it, play the game, or go out and do your own thing.
