Why bother with 2-3x more air pressure and all the problems that go with it (crew decompression, lack of abort options, etc.) when the outside pressure is hundreds or thousands of times more? You're really not gaining anything engineering-wise.
One thousand times would make it 10km depth - so clearly not “thousands”. Other than that you are right that there is no gain in e.g. doubling the internal pressure.
Yes I made a mistake in my estimation there. Max pressure at the challenger deep is about 1,000 atmosphere, so that shouldn’t have been plural.
