More people or things contributing to a goal does not always add more security/efficiency/capability to achieve said goal.

A classic example is a length of chain.

The more individual links, the more weight the chain as a whole needs to be able to carry.

Each link needs to be able to support the weight of the load and the weight of the entire length of the chain.

More links also introduces more opportunities for links with failure points to be included.

I choose to believe that that is not a list of three similar things, but a list of different ways to be remembered.

Do you want to be remembered as dilettante competing in a crowded field who managed to have the right combination of skill and luck?

Do you want to be remembered as the one collosal idiot with a cult of personality, who claimed to work for humanity but only ever dipped us into a kessler syndrome and helped set the conditions for the Bell Riots?

Do you want to be remwmbered as the inventor of a revolutionary technology in desperate times that single-handedly averted the doomed fate of humanity?
