To truly answer such questions you should have a (set of) metrics to measure what is better and run parallel universes for a significant amount of time to check which version is better according to your metrics.

>> Think of all the fossil fuel infrastructure, wouldn't it be a waste to stop using it?

Most likely, it would be a waste to stop using it right now.

>> Your goals and goals of your genes are not the same. You should care about as much about your genes as your genes care for you (not at all)

Living organisms are genetically wired to care about their genes, e.g., to express them (e.g., to write posts on HN and publish scientific papers) and spread them (to have kids).
