I never really cared about making more than $5m until I realized that the profit motive[0] is going to destroy everything because it dumps everything into arms races and as human power goes up, due to increased scientific advancement and the accelerating search space for technological combinations that provide greater economies of attack asymmetry, negative externalities begin to dominate the world. Especially in areas where attribution is impossible, since deterrence isn't possible, or in areas where outcomes are unpredictable, for the same reason.

I just wanted to have fun and create a little garden for myself. Now I have to become some ugly combination of Soros, Orwell, and Nader[1] because the people with money right now are all people that cared about money, or—ethically better, but consequentially worse—they're techno-optimists.
