Yea - high dimensional spaces are weird and hard to reason about... and we're working very frequently in them, especially when dealing with ML.

Luckily if you do enough math it becomes much easier to reason about such spaces

- How do you even visualize an 11-dimensional space?

- oh that's easy - you just visualize an N-dimensional space and then set N equal to 11.

Yeah, stopping that need to visualize everything is one of the mechanisms usually adopted for working in high-dimensional space.
