That's a great result, given the state of the art back then!

I never timed myself; it never occurred to me at the time to compete.
When I started, there were not even books available, let alone tutorials.
But am now tempted to see if I can learn new tricks and progress at all.
Time/dexterity is now everything, since algorithms seem to be totally optimized and
well known.

I believe they have 10-15 seconds for examination, but what counts is the actual
action. Some kids don't even use up those 10-15 seconds; they grasp the
configuration instantly, it seems.

I've forgotten the cube for a few decades and was astonished to
see how the scene has changed. There seems to be a revival, but how far can
humans go?

This LEGO robot does it in 3.5 seconds:

Indeed. Humans are amazing.
