This is an upper bound not a lower bound. That roughly means that whenever you don't have proof to the contrary you assume the worst.
What? Cousin_it gave an upper bound. I (and timtyler) are pointing out a plausible way the value could be significantly below that upper bound.
The most simple, able to self-improve "seed" for a superintelligence must be how complex?
Give your (wild) estimation or a pure guess in the terms of bits.
Do you reckon it is 1000 bits enough? At least 1000000 is required? More than 10^20 bits?
I wonder what your approximate numbers are.
Thank you!
