There’s a lot of other variables at play for humans. Like

- the need to sleep for 1/3 of our life

- the need to eat, causing more pauses in work

- much slower (like several orders of magnitude slower) data input capabilities

- lossy storage (aka forgetfulness)

- emotions

- other primal urges, like the need to procreate

Imagine never forgetting, and never getting bored or tired. I think we could achieve a lot more.

meatspace constraints!
