Humanity might have another wheel type invention I suspect. The first wheel helped us evolve, it allowed us to build civilisation, cities, employment, travel, education, etc. I think of the plane as an extension of that wheel, and also the spaceship, movement. I can only guess at what the next wheel might be.
The most important invention since the wheel was the computer, perhaps a wheel type invention. Our invention of money is such an abstraction from our understanding of value. I don’t mean economic value, I personally value travel, honesty, love… Money was not a wheel type invention. AI is I think, the most significant invention since the wheel. Did the wheel or language come first?
