Bailouts have been a wonderful tool in the 21st century. During 2008 crisis, there was an unbelievable high ROI to them, both in the $ value of investments in the banks and in the global economic catastrophe it prevented.

Who is more impactful, the startup engineer who singlehandedly ships a feature that increases a startup revenue by 25% off a base $5M/yr ($1M extra rev), or a Meta/Google team of 5 engineers who ship a .01% revenue improve off a base of 150B/yr (15M/5 = $3M/engineer).
As an engineer you are thinking about impact as 'scope' or 'features'. Leadership will be thinking marginally on what adding a net new engineer will provide to the business.
“Marginalism is the economic doctrine that we can best understand value by considering the question of how many units of a good or service an individual has, and using that starting point to ask how much an additional – or marginal – unit would be worth in terms of other goods and services.”

What field has interviews without silliness like this. Jobs for lawyers in 1950 when all that mattered was your father and your alma mater? Hard pass.
I would take a interview premised on a know, learnable challenge (even if silly) over one that exclusively relied on what college you went to.

The native tool use is a game changer. When I ask it to debug something it can independently add debug logging to a method, run the tests, collect the output, and code based off that until the tests are fixed.

Living off 20k a year in a Hcol, where these salaries primarily occur, is next to impossible. Rent alone anywhere in SF area, for example San Jose, is 2k at a bare minimum for a 1BR, or 3k for a 2BR split between a roommate at 1.5k each. That means rent is 18k-24k, not to mention other living expenses (car, utilities, food, travel to visit family, etc.)

Is there a OSS license that specifically precludes its use in LLMs or effectively does so?

Twitters data cannot fit on one machine. In 2015 their Hadoop cluster was 30 PB per earlier comments/their blog. How do you fit that on one machine?

They did not spend half their revenue on compute. It’s more like 20-25% for running data enters/staff for DCs. Check their earnings report.
Whats app is not an applicable comparison because messages and videos are stored on the client device. Better to look at Pinterest and snap, which spend a lot on infra as well.
The issue is storage, ads, and ML to name a few. For example, from 2015:
“ Our Hadoop filesystems host over 300PB of data on tens of thousands of servers. We scale HDFS by federating multiple namespaces.”
You can also see their hardware usage broken down by service as put in their blog.

Excluding a settlement from 2014 that was paid this year, Twitter would have made 500mil on 5B revenue in 2021. They were also GAAP profitable in 2019.
Additionally, the incentive from wall street is to spend all your money to grow users. Whether that is right or wrong it’s the path they chose which led to users and revenue roughly doubling over 5 years.

SRE is a mix of both. The expectation is you are able to write and understand any code the team is responsible for.

Yes that is the normal case. The post was refuting the assertion that one engineer can run these services indefinitely as previously the OP had the help of SWEs oncall and also fixing bugs.

One SRE, many SWE. Also have fun asking someone to be permanently oncall with one person on the team.
The cache clusters size are also described here for anyone who wants a good technical read over speculation. https://www.usenix.org/system/files/osdi20-yang.pdf

But Tesla and Spacex have notoriously low pay compared to their peers. Eg a Tesla swe makes 40% less than at Google
