10k? 100k? A million?
I am not talking about calculating with numbers, but rather the point where numbers stop being comprehensible, or “no longer mean anything”.
Try visualizing exactly 10000 apples in your mind.
Edit: What I’ve gathered so far from the answers:
Visualizing: <10
As an average, I usually see the number 7 bandied around. After that we start “chunking” where each group becomes its own conceptual object.
This is why phone numbers without the area code have 7 digits in North America.
That’s not quite the same thing - the 7 digit phone number has more to do with short-term memory capacity than visual perception. Miller’s Law of short-term memory is we can store 7 +/- 2 items at a time, depending how complex they are.

Oh, I was way off, then.
