its terrible for any number of reasons, but i think if we invent immortality there should be an extreme sport called civilizational speedrunning where teams of 20 go into the wilderness somewhere and try and be the fastest build the first internal combustion engine. i bet you could get it down to like 3 years tops
The real trick is to eat seed heavy food before the speedrun starts so your first poops are halfway to agriculture already
i want you on my team holy shit
