"After two years at Queen's University, Musk transferred to the University of Pennsylvania. He took on two majors, but his time there wasn’t all work and no play. With a fellow student, he bought a 10-bedroom fraternity house, which they used as an ad hoc nightclub."
You've bought the CNBC fud. Tesla made 4x the profit from cars than bitcoin or credits. Valuation is based on the future, not on the past. Exponential growth matters - just look at the last ten years, then extrapolate a few years more. If you did not predict 500k Tesla cars delivered in 2020, back in 2015, then you can not credibily comment on current valuation ( which is based on the future).
If you extrapolate, VW will overtake Tesla soon in electric cars.
The reality is more that untapped markets follow S curves. The electric car market will not be bigger than what the total car market has been but replace it. Electric cars are not there yet, but the market valuation is already far beyond that.
Tesla made 438 millions profit, 100 million are from bitcoin.
If we ignore the profit from carbon credits (they made more from credits than from bitcoin)
they made 4x100 millions profit from cars by your math.
So combined they made more profit than they did.
What comes next? Are they building the perpetual motion machine?
Well I guess that depends on what you mean by “true immunity”. If you mean not a single cellular infection, then that is ridiculous since true immunity doesn’t exists.
If instead you mean that you develop no symptoms, and cannot pass on the virus, then they indeed can and do (which is why r naught drops).
Now obviously if your “high viral load” is being literally bathed in viruses... then ok. But for many situations, typical viral load and even high viral load situations as seen in health care settings, many vaccines would qualify as giving large percentages of people “true immunity” in the sense of no symptoms and no viral shedding.
Another thing vaccines can do is prevent illnesses caused by toxins. In those cases antigens of toxic compounds generate antibodies to incapacitate a toxoids effect on the body, for example the tetanus and diphtheria vaccines or vaccines against rattlesnake venom.
Doesn’t seem like that condition leads to termination. As things return to normal, fewer surveillance tests will be conducted by definition, so the test positivity rate will rise.
In BC we've learned that we need to distinguish between the positivity rate for "testing due to symptoms or known exposure" and "testing for screening" (e.g. the film industry tests all their crew daily). The former positivity rate is much higher, but the latter may be more useful as a long-term trendline to follow.
Test positivity is a weird metric because of things like this. It's interesting week-over-week, but loses meaning over the long term as testing protocols, other behavior changes, and changes to the disease. This makes it a lousy metric for policy making.
There was a county in Louisiana that went back into a shutdown Thanksgiving week, when nothing at all had changed, except that a local university was on break and had stopped flooding the daily statistics with thousands of negative tests.
Not to mention the perverse incentive: if you feel sick, you want to avoid getting tested and counted as a positive if you don't want your locality or employer to shut down. There is a theory that this accounts for much of Japan's perceived success - antibody studies show just as much prevalence as everywhere else, what happened was that all the mild cases never got tested.
There are also non-perverse incentives. If I feel sick and live alone, a test test result doesn't give me much actionable information, takes time, and puts the people giving the tests at slightly more risk.
Musk's only compensation for Tesla is related to share price. He is therefore doing everything he can to take a large market share from the incumbents - they have had 8 years to respond to the Model S, and have done nothing.
