Cells certainly utilize a variety of currencies, mostly energy in various forms.
Energy is a resource, not a currency. Cells don't trade amino acids for energy with each other.
I'm pretty sure an anthill or a termite mound has some feedback systems which control the foraging of ants and termites.
Probably, although we don't fully understand them. Also feedback systems =/= currency.
You're not paying attention. Let me try again: INFORMATIONALLY equivalent. Do you understand what the INFORMATIONAL role of money is?
Besides, "resource" and "currency" are not mutually exclusive. Until relatively recently currency (e.g. gold coins) had intrinsic value and so was a "resource".
How much money would it take to engineer biological immortality for at least half of the world's population, within 20 years, with 99% confidence?
