Things still cost money. There are always scarcities. For example cells already reached exponential self replication capabilities long ago, but eventually hit environment constraints. It became a struggle for survival, but under infinite resources they would infinitely replicate without effort instead of evolving.

Don’t worry, the AI cokeheads have told me that LLMs will usher in Star Trek post scarcity.

We're much closer to modelling cells than humans, yet we still pretend like we're already there somehow on both accounts.
