The discussion of billionaires building "CERNs" came out of a discussion I was having with a friend as a way to quantify how rich these people are in terms more understandable. Graphics like pixel wealth[0] just show scale, but doesn't put things in perspective. But a Forbes analysis estimates the cost of finding the Higgs at around $14bn (rounding up)[1]. I also tried using Super Computers, but at around $300m a piece the number was too small (e.g. Elon is 100 Auroras and Bezos is 1000, ball parks). Number of CERNs became a much more approachable metric but also has the fault that these take over a decade to build (meaning the # of CERNs is likely an underestimate).

I do agree that this would be a great PR move. Especially as we've seen Bezos grow his wealth by $65bn in the last 4 months[2] or Elon by $44bn (more than doubling) in the same time frame[3]. But the practicability is also a little naive considering that these numbers do not equate to liquid cash that they have available. Though someone like Gates has much higher liquidity than Bezos or Elon.

But it is interesting. Maybe if my metric catches on someone will build one (or another mega science project) :D
