not sure it invalidates my claim, but maybe it does.
I would argue that to a cuber, all cube positions are meaningful.
Just the fact that they're random doesn't mean they're hard to
memorize/recognize. But maybe it is somehow fundamentally a much
bigger harder problem in some way.
It would be interesting to know how the number of possible
"meaningful" chess positions compares to the number of possible cube
positions. Not that that conclusively proves anything, but it's an

I got the "fraction of a second" from memory, and as you found that
memory was a exaggerated by a factor of 10. Make your own 'irony' joke.
Are there any other comparable cases of instant recognition that
people do? I haven't had my coffee, so I can't think of any. I'm
thinking less of conscious memorizing of symbols and more about
things that plugs into our instinctive abilities. That's often
thousand of times faster.

I read that "roux cubes" were very useful in cooking too, but I don't
know exactly what they are. Some funny quotes I found on the web:
- "I used a quick roux substitute method I'd read about on another
- "Many Cajun grandmothers have switched over to instant roux because
it is easier and quicker".
- "I suppose you could make a roux in the microwave, and I guess that
with practice you can learn how to do it properly. But it seems like a
pretty dicey proposition to me."
Roux is such a common name (about 60000 Rouxes in France), it's not
very surprising some have given their name to things like cube objects.
