Aren't we still those people? Aren't stone tools, and tools made of wood, bone, and other plant & animal parts, enough? They don't require smelting (though I wouldn't be surprised if someone(s) 10,000 years ago got curious about the metal bits in their fire and traced it back to iron deposits in the sediment stuck to the wood gathered from a dry riverbed), and are far less environmentally damaging than a lot of the stuff we make these days.
Numerous other animals make and use tools, and plenty others don't seem to, and they get by okay- a meaningful life can be lived without the technological trappings we've cocooned ourselves in.
I take neither this phone nor reading and writing for granted; it's all wonderful and unnecessary technology. Who needs to read & write when you are part of a tight-knit, mutually-supportive community with a rich oral tradition going back millennia?
