@EricTopol @BMJMedicine How is age considered in this analysis?

The universe is a beautifully consistent system of rules. Intelligence is the efficiency with which you can go from the output of these rules (what you can observe) back to the rules themselves.

A thread about what is wrong with the influence of Elon Musk and other tech billionaires. Another thread about content moderation will follow later this week.
Obviously, the problem isn’t that Musk is expressing his opinions, which is his freedom of speech. It isn’t that Musk has turned into a big supporter of Trump. It isn’t even that Musk is posting AI-generated fake images of Kamala Harris: https://t.co/1vprj7i0at
My concerns are more sociological and political economic.
My starting point is that in any society some individuals have more, much more power than others. Once upon a time, this may have been linked to physical strength or military prowess. Today, it is often related to what Simon Johnson and I called “persuasion power” in Power and Progress.
https://t.co/NtJ8Ae60qr
Persuasion power is rooted in status or prestige: those with greater status can more easily persuade others. Where status comes from and how unequally it is distributed vary greatly across societies.
In the United States, status became linked to money and wealth, and income and wealth inequality skyrocketed. This meant a very steep status hierarchy.
That is problematic for several reasons.
First, status – and relatedly persuasion power – are largely zero-sum affairs. More status for somebody means less status for another. A steeper status hierarchy makes some people happy, and others unhappy and dissatisfied. Investment in zero-sum activities is often inefficient and excessive, as compared to investment in non-zero-sum activities. Compare, for example, the social value of spending money on pure gold multi-million-dollar Rolex watches versus spending time to learn some new skills. Both may have intrinsic values for the investors (due to the beauty of the watch and the pride of acquiring new knowledge). But, on the whole, the first type of investment signals that you are richer and more able to undertake conspicuous consumption, and it can easily get out of hand – with people spending huge sums in order to edge ahead of others they see themselves in competition with. The second type of investment, on the other hand, increases your human capital also contributes to society. The first is largely zero-sum the second is largely non-zero-sum.
Second, there are evolutionary and social foundations for linking persuasion power to status and prestige – it is individually rational to learn from people who have expertise and it is reasonable to link this expertise to success. This type of learning is also good for communities, because it enables them to coordinate on certain best practices.

But when status gets linked to wealth and wealth inequality becomes very large, this social justification is lost. Consider the following thought experiment. Who has greater expertise on carpentry? A good, master carpenter or a hedge fund billionaire? If we think about it this way, we would probably conclude the former. But when wealth becomes status, we may start attaching more and more importance to views of hedge fund billionaires on carpentry. This example was purposefully simple and sharp. Let’s take another one to see why the “wealth is status” social equilibrium is problematic. Whose views on freedom of speech you want to attach more importance to? A tech billionaire or a philosopher who has grappled with ethical questions related to the freedom of speech?
Third, even more problematic is the fact that in most societies, wealth inequality has an arbitrary dimension. Take Wilt Chamberlain and Lebron James. We may argue endlessly about which one is better, but clearly, they were both exceptionally talented basketball players. Chamberlain is estimated to have had a wealth of $10 million at the time of his death. Lebron James’s wealth today is estimated at $1.2 billion. These different outcomes are largely arbitrary. Chamberlain happened to live at a time when there were sports stars did not get compensated as much. This is partly about technology (everybody can watch Lebron James today), partly about norms (we’ve have made it much more acceptable for people to be paid hundreds of millions of dollars), and partly about taxes (if the US today had the kinds of tax rates that it had in the 1950s, it would not generate such large wealth inequality). Similarly, if the tech sector did not become so central to the economy and did not have a winner-take-all aspect (which was also partly a choice of how we organize several markets and sectors), tech billionaires would not have become so rich. Bill Gates or Elon Musk are not any wiser because they are taxed less. But they have much more wealth because they are taxed so little. But then in a “wealth is status” social equilibrium, their status and social influence multiplies because they are taxed so little.
Fourth, there is something even more pernicious which Simon Johnson and I explored in Power and Progress using the example of Ferdinand de Lesseps. In fact, we thought this was so important that we devoted the first full chapter, Chapter 2, of the book to it. Lesseps gained tremendous status in late 19th century France, coming to be identified as the “Le Grand Français” (the great Frenchman), because of his success (and luck) in successfully completing the Suez Canal. He showed great skills in convincing politicians both in Egypt and France and some foresight in seeing that maritime international trade would become very important. He was also tremendously lucky in that his hopes that technological solutions to the way that he wanted to build the canal (without locks, which was initially impossible because of the amount of digging excavation that would be necessary) were developed just-in-time to save the project. But then what did Lesseps do with this prestige? He became reckless, unhinged and cocky, pushing the Panama Canal project in an unworkable direction, which ultimately led to the deaths of more than 20,000 people and to financial ruin for many more (including his own family). Persuasion power also makes you unrestrained, which can be socially dangerous and disruptive. Simon and I thought that Lesseps’s story was relevant precisely because the same dynamics were being played out with many tech leaders today.
Fifth, some very rich people choose not to use the status conferred on them by their wealth to centrally influence critical debates (think of Warren Buffett). Some like Bill Gates or Elon Musk do. It follows as a corollary of what I have argued so far that this is not desirable, because their status is excessive, and they are now influencing key social choices beyond their expertise. It is not tech billionaires’ fault that US policy is fueling massive inequality (though they benefit from it handsomely and many of them then use their status in order to keep taxes low and regulations light). But it is their responsibility if they start misusing the huge status that this wealth inequality affords them. It is their responsibility if they turn into bullies and start punching down on people who disagree with them, because they themselves start believing that everybody should respect their opinion on every topic. It is absolutely their responsibility if they use their platform for further polarizing society.
Finally, if we are in such a situation the last thing we want is to give even bigger forums – for example, in the form of their own social network – to these people who already have excess status and influence, and this is doubly true if they have a tendency to punch down.

@WallStreetSilv Back when I worked for Exxon there was a proverb about this sort of thing: that a healthy oil company had a geologist in charge, a mature one had an engineer in charge, a declining company had an accountant in charge, and a dying one had a lawyer in charge.
