> All of these examples are done by specialist because I don't see many cars being build by dentists.
I'm not sure how you get from pre-agricultural humans developing fire, to dentists building cars.
I don't doubt that after fire was 'understood', there was specialisation to some degree, probably, around management of fire, what burns well, how best to cook, etc.
But any claim that fire was the result of specialisation seems a bit hard to substantiate. A committee was established to direct Thag Simmons to develop a way to .. something involving wood?
Wheel, the setting of broken bones, language etc - specialisation happened subsequently, but not as a prerequisite for those advances.
> Even in mankind's beginning specialization existed in the form of hunter and gatherer. This specialization in combination with team work brought us to the top of the food chain to a point where we can strive beyond basic survival.
Totally agree that we advanced because of two key capabilities - a) persistence
hunting, b) team / communication.
You seem to be conflating the result of those advancements with "all progress", as was GP.
> The people making space crafts (designing and building, another example of specialization) don't need to know how to repair or build a microwave to heat there for food.
I am not, was not, arguing that highly specialised skills in modern society are not ... highly specialised.
I was arguing against the lofty claim that:
"All progress we've made is due to ever increasing specialization."
Noting the poster of that was responding to a quote from a work of fiction - claiming it was awful - that the author had suggested everyone should be familiar with (among other things) 'changing a diaper, comfort the dying, cooperate, cook a tasty meal, analyse a problem, solve equations' etc.
If you're suggesting that you think some people in society should be exempt from some basic skills like those - that's an interesting position I'd like to see you defend.
> Of course everybody still needs to know basic knowledge (how to turn on microwave) to get by.
FWIW I don't have a microwave oven.
