This Quora answer talks about what disposable income you can expect from $5M (about 5%) vs. $100M (About 8%).https://www.quora.com/How-is-being-a…/answer/David-S-Rose
I’d put $50M in diversified investment and expect $2M to $4M from it annually. This would take care of most luxuries I want in life, such as a personal chef, a masseuse, housekeepers, (renting) an artificial wave machine, (renting) a fancy car, buying houses and fancy things for my parent, etc. The rest would be play money to make bigger differences in the world and take fun risks with!
I’d get to know influentials and rich people and see how they spend their money. I’m sure at that level you get to see another side of the world.
I’d build an advanced science and technology theme park, complete with hyperloop rollercoasters, simulated moon landing, mars tours, space travels, and other extraterrestrial adventures. It will also demo the latest technologies, or Tesla inventions.
I’d build experimental houses and buildings to explore good ideas, such as ones that maximize energy efficiency using different techniques. One of them will have transparent floors and ceilings, so it gets sunlight all the time. It’ll have artificial sunlight too.
I’d invest in robotics in the hope that we get sex robots sooner.
I’d invest in VR. I want to explore a VR world and have fun in it.
I’d start a restaurant despite it being the biz with the highest failure rate. One idea I’ve always wanted to turn into reality is a restaurant in a giant dome, with sky and simulated environment projected onto the dome. As you eat, your environment (the dome wall) changes from sunrise to sunset, from one country to the next.
