That question became Ethical Crossroads (originally Ethics in Entrepreneurship), a way to make ethics practical, approachable, and actually useful to the people making the calls. The technologies we're building now are more powerful than anything I watched fall apart. The harms go beyond one company's patients or one industry's investors. The cost of carelessness can pose serious catastrophic risks that humanity can't walk back from. Today, that work has taken me to the frontier of AI ethics, safety, risk, and biosecurity.

I work in ethics not because I think people are bad, but because I've watched good intentions flounder when pressure runs high, and when people face the hard decisions alone. I've stood at the crossroads myself: unsure, afraid, and acting anyway. Now I work on the most personal mission yet: building a world in which our children will flourish.
