What happened to nerds?

The points your making make sense. I am thinking of it like this: Say there is an elegant argument. It checks out at first. Then you do the unit analysis, and find out the units don't match! But you still don't find the flaw in the original argument; maybe because it's suble in some way. That's where I am: Very smart people have been writing things in the vein of your post here for millenia, and it always seems convincing in the light of contemporary knowledge! Then is proven to be incorrect by major advancements.

Perhaps this will help: Indeed high energy physics is a very high budget project! But there are many areas of the natural sciences which are not high energy physics. This area has been a big deal over the past few decades, and I wonder if it's an over-commitment at the expense of other areas.

You can do many molecular bio lab techniques with a budget of $10k in equipment and reagents, for example. (If used/entry level) I believe there are also many areas in science, chem, and bio which can be done on a theoretical level, or with computers, etc.

Another angle: We are in the earliest steps of neuroscience. Many biology tools and techniques are borrowing something serendipitous we found in nature (CRISPR, TAQ polymerase etc, leveraging living cells' equipment to produce proteins etc). We have no concept of a general chemistry simulator. Molecular dynamics simulations can only work on very small systems for very small timescales, and are based on many approximations, and assumptions which provincialize them. We are very likely missing a big picture of the lower levels of GR/QM. It is very hard for me to agree with "Yep we're good; nothing left to discover here without really expensive equipment!".

Both terms are overloaded, because neither has been used with any consistency. Like the long forgotten trekkie/trekker divide, it was a way for some people to feel superior to other people, but the lines were never clear.

People succumbing to parental pressure become doctors.

A lot of folk go into teaching because there's high demand for workers & the academic path is relatively accessible.

You're probably mostly right about social workers, but it's a vague term & there's at least some categories of social worker that fill the same appeal as teaching.

Virtuosity is so hard to define, I'd say there's some virtue in almost every career direction but less in some than others. Certainly in my experience tech entrepreneurship has some of the lowest levels I've encountered.

The OP is mostly talking about image, not reality. What image do tech founders choose to project.

OPs timeline is somewhat off. They posit a golden era for the 1980s-2007 but that’s not right. Tech CEOs have often been hard-charging salespeople and businessmen. Look at early Wired magazines and there was much celebration of random rich guys in suits, as much as the nerdy tech creators. This was the “suit/hacker” dichotomy.

Google was the company that really exploded that paradigm, from their rise to prominence circa 2002 or so, to their IPO and post-IPO halo, around 2005-2007.

Now the nerds didn’t need the suits. They would run their own company.

They were shockingly wealthy and powerful but it was made to seem as a kind of distraction from their true nature. They marketed their own virtue and renunciation, both to the public, and to their own staff. Their business model rejected the previous search engine paradigm (backroom deals and paying for placement) in favor of a new one (complex math to produce the best results). They told the public and their staff the famous “don’t be evil”, and also “focus on the user and all else follows”. There was even a pronouncement that Google would never do such tawdriness as horoscopes.

The theme was that nerdiness was a kind of incorruptibility because a nerd was honest, unconcerned with social status, and unworldly. Let them into your life and they’ll make it all better. Larry Page and Sergey Brin cultivated that image, holding internal and external events where they made themselves look ever nerdier than they actually are, even wearing lab coats.

Now, this didn’t last and was never true. Soon after the IPO, Larry and Sergey bought themselves not just a corporate jet, but a commercial airliner. They justified it as something that was “good for the world” because they could use it to get entire teams of NGO workers on missions of mercy. It actually became a party plane, as far as I know.
