What do self-made billionaires say about the best industries to invest in right now?

The billionaires and millionaires interviewed point to a few areas. One venture capitalist said AI is the big opportunity and urged people to learn everything about AI and start building with tools like Claude code. A Silicon Valley entrepreneur said cyber is going to be hugely important because AI makes it easier to fake everybody out, and he pointed to switchgear and energy infrastructure, where he said demand is so high it can't be met. A Jamaican-born investor said there is a shift occurring towards nuclear energy. A Nigerian stock exchange leader said AI is a path for the future but that agriculture is the next frontier in Nigeria. A Monaco investor said AI needs power, so anyone who can generate sustainable energy to feed it is where you want to be. The oil and gas operator said natural gas, not oil, is where he is focused, calling it the cleanest burning fossil fuel and tied to data centers.
