I think that this sort of perspective is (at best) a-historical. I have absolutely no clue how difficult it would be to actually conceptualize "rope" or "wheel" without any of my modern knowledge.

The saying that 'hindsight is 20/20' would seem to be particularly true at the scale of early human invention and civilization.

  Good luck with making your own wheel or rope from scratch (i.e. alone and naked in the woods)!

This comment (by my interpretation) implies that the process is difficult. I agree with other comments stating the concept is difficult, but the process for those two inventions is quite manageable - even if you are "alone and naked in the woods".

Exactly. The invention isn’t the physical object, it’s the idea - the realisation that a certain class of objects/processes can be useful in unexpected and open-ended ways.

Wheels are almost useless in dense forests that have no roads, for obvious reasons. So why would anyone waste a day or two making one?

Wheels are one thing, axles and their bearings and lubrication are another.

> take a large piece of wood and whittle away until you have a wheel

This does not resemble the actual construction of any but the smallest wooden wheel for toys.

You don't think this is how they built the original wheels?

I'd prefer to rely on archaeological evidence rather than retroactive first principles; for example http://www.culture24.org.uk/history-and-heritage/archaeology... which shows a panelized wheel. I see SciAm have an article on the difficulties of a useful wheel too: https://www.scientificamerican.com/article/why-it-took-so-lo...

You can't make a useful wheel out of a single large block of wood. It will dry out and crack. Wooden wheels are made of several pieces to minimize this problem.

You are describing a more complex wheel already.

The first used wheel bas probably some vague round stone with a hole it it.

It sucked, but it was better than no wheel.
