@deshipu There are many interesting uses of wheel other than transportation, surely even in Mesoamerica they put some of them into service. For example, wheels give you mechanical leverage, and also mechanical power if appropriate extensions are attached (handholds, flat surfaces for pulling energy from river flow and wind).
@deshipu My point is that it's a constant of humanity to seek solutions to one's problems. If a technology can solve someone's problem, it'll be used. If it's close enough to be a solution, it'll be worked on until it solves that problem - at which point it may be close enough to solve a host of other problems for someone else. This is a big driver of technological progress.
Conversely, if it isn't close enough to be a potential solution, it remains undeveloped until conditions change.
