How are you going to have a single Chess Grandmaster alive on the planet? Who will they play against to learn? Whom will they compete against to get really good? Where will the enthusiasm and education come from to get them interested at all? Who will their peers be to certify them as any good? If you need two people to lift a heavy weight, it's not possible unless their lifetimes overlap enough that they are both strong and healthy at the same time. Insects with individual neurons alive for a billion years didn't produce a single technological invention. If you need a civilisation where some group digs iron ore, some group processes it into steel, some group processes that into sheets and pipes and tools and valves, some group processes those into chairs and desks, some group uses those to build computers, some group uses those to build wind tunnels, some group uses those to build rocket engines, some group uses those to build rockets, some group uses those to build satellites ... it wouldn't work if your only source of plate steel was 1,000 years old and your only source of valves was some weird pile of leftovers from 500 years ago when they didn't understand your use case at all, and if you're plans for your rocket are that someone will fly it 200 years after you die...
