I believe what makes humans powerful is written language. It can survive generations and can be copied and shared. That power leads to someone figuring something out halfway, and someone evolving it into a working piece. Then someone comes and evolves the technique to a blazing efficiency. Plus writing allows trade to occur because we can keep verifiable accounts. This leads to specialization and trade where efficient tools propagate really fast. Seeing written language and trade in any other species would mean they’d evolve their technology real fast.
