I agree that "net worthy" is not an ideal value of a person.
However, I am not sure we have a better way to value people at the moment in the global market.
Fortunately, it seems we are mostly in a post scarcity world, where there should be enough shelter, air, water, food, and productive social things to do for everyone in the world.
Unfortunately, location, due to various factors, might limit some people in the world from enjoying all those benefits, but I would assert without provide much evidence sorry, that we are better off now then most of human history in providing for people's needs.
To further stir the pot I will also claim this is due to capitalism, or essentially valuing people by their earning power and monetary wealth.
But I do confess, it seems we can do better, and the "system" is not without corruption; but still better than other systems attempted.
All of this is a wonderful debate probably too much for this forum, but I would love to hear proposals for other ways of assessing the value of a person; if that is appropriate at all.
All that aside I was more motivated by the Taylor Swift vs Elon vs 10,000 builder assertion in your comment.
I am not much of a Taylor Swift fan, nor have I ever really gotten to excited about a performing artist of any form to the level that "Swifties" appear to adore Ms. Swift. However I do confess I have song along to a few of her songs with the radio and have enjoyed them. The "Swifties" obviously value Taylor, and their enjoyment perhaps enhances their lives and makes them more productive, all kinds of positive things. But I agree if she dies tomorrow not many will be worse off, a few days of mourning, and her songs will still play just as well on Spotify and a new singer or ten will fill the void. Nothing of value will really have been lost.
But I am not convinced the same with Elon. I understand hating Elon is popular these days, but I am not convinced of that either. However, it does seem that he is more than a one trick pony, and I believe it can be argued that had Elon died twenty years ago the world would be a different place. I cannot say the same for Taylor Swift. I have had the pleasure of driving a Tesla a few times, and love it, have not spent the money on one yet, but would love to own one. I am not sure on the numbers, but I am not sure I could point to another car company that sprung to life only in the 21st century and has had such success. The Ford, GM, Dodge, Honda, Toyota, BMW, Volkswagen, Mercedes....are all pushing 80 to 120 years old, kings, and Elon's Tesla disrupted the market in what I would say is a positive way. I have not found another EV I would want from one of those old school manufacturers yet.
Beyond Tesla, I want to address the assertion that Elon did not develop the Space X rocket. I recall seeing a video interviewing a rocket scientist or something, talking about Elon getting the books and actually learning and proposing designs for the rockets. Now without the 10,000 engineers I am sure he would not have gotten out of orbit. Not to mention Space X appears to be the leader vs Blue Origin, Virgin Galactic and other commercial ventures.
I am sure there were other internet satellite systems out there before Starlink, but I had never heard much of them before.
I am an LLM fan, and I understand that Elon deserves a ton of credit for forming OpenAI. My understanding is that Google made the breakthrough with transformers in 2012, but OpenAI, a company that did not exist until 3 years later was created and beat Google and every one else to the punch.
Electric vehicles, commercial space travel, satellite internet, LLMs would probably all be a thing to some extent had Elon never existed. But I am not sure that they would be as good today or accessible in a world without him. I am not convinced that Elon is simply a rich guy making money off the backs of a bunch people actually doing work.
Now I am not convinced Elon is quite right on Bitcoin after hearing him talk on that matter. Plus it really seems questionable to have bought Twitter. Plus Sam Altman ran off with OpenAI and upset Elon. But you had to cite "10 thousand builders" dying to make an overwhelming disruption compared to Elon, not one builder, not ten, a hundred, or even a thousand, but ten thousand people's death is what it might take to disrupt the world vs one man, or maybe that comparison was aimed at the value of Taylor Swift...I am not sure ten thousand is high enough actually, we may find that ten thousand electricians, plumbers, carpenters leave the work force in a year due to retirement and death, and the world keeps progressing forward with another ten thousand or twenty thousand to replace them without missing a beat.
That is a lot of rambling, but I feel better now; thanks for reading this far.
