Web3/Crypto: I was always kind of septic about it, and I believe there is still more speculation than value. I like the angle of trust vs efficiency, and started appreciating more once I come across the example of Democracy as way that we feel better to operate a society and lead to better results, even if is less efficient than an autocracy.
Religions: I was raised catholic but never really bought into it. Although I consider myself an atheist now I find religions were one of the best Human inventions and there is a lot to learn from them. I spend time in Judaism and Hinduism, going now over Muslim.
How humans work: Learning the little that we know about our species, from psychology to biology, trying to understand how to do better in this world.
