100k feet in altitude may not be quite high enough to get that 'in space' feel. I think you can see the curvature of the earth and the sky above you is dark / blackish.
I'm not sure it would have much of an adverse impact. Driving the car is constantly charging / discharging it (regen braking).
I think it's more about how deep the cycles go -- just don't let the grid drain below like 30-40% battery and it likely would have no meaningful impact long term.
I'm not sure it a totally rational thing. This is effectively putting more miles on your battery, an item that costs tens of thousands of dollars to replace, if even possible years after purchase. There would have to be a substantial compensation for such use even if it only degraded the lifetime a few percent.
But at such a compensation level, one could probably just purchase deep cycle lead acid marine batteries. They could sit in one's basement charging/discharging at a much lower cost than the lithiums in a car.
The price of batteries has declined by 97% in the last three decades:https://ourworldindata.org/battery-price-decline. And it continues to go down! The chart ends at 2018, $181/KWH. 2024 forecast is $94/KWH (half of 2018 price), 2030 forecast is $62/KWH. Thats just Lithium Ion. Newer chemistries are even cheaper. CATL first-generation cells (Sodium Ion) cost $77 per kWh, expected to drop to $40/KWH.[1]
Current estimate for a battery replacement is 4K - 20K. With energy storage's learning curve, this will be soon under $3K.
> Driving the car is constantly charging / discharging it (regen braking).
My understanding is that the impact on battery longevity relates to the rate at which it is being charged/discharged. Accelerating and regenerative braking are small potatoes compared to charging over a typical level 2 system, I would think.
A typical L2 charger will provide in the range of 6-10kW (AC, marginally less ends up going to the battery after conversion losses). 10kW is only 13hp; forget acceleration - the car draws more than that at highway speeds.
(You can come at this result another way too - an L2 charge may take 6-10hr to refill the battery from empty. But the car would not be able to drive 6-10hr at highway speed starting at 100% charge! So the L2 must be delivering less power than the car consumes at cruising speed.)

iPhone solutions seem less advanced, unfortunately, but they exist. Personally I use one called "Adblock Pro," but that's not an endorsement, just the one I tried that has stuck.
I don’t think this post is trying to use correlation to prove causation. It’s in effect saying that when you can’t be sure that there is a causal relationship between two things that you can still make some decisions.
Based on the filing the company awarded 42M stock options to the CEO earlier this year. The filing mentions a share price of $110 per share, so that's over $4B.
That can't be normal, right? That's 10% of the entire company. It's more than Elon Musk got for Tesla by a long shot, and that was already controversial.
Options require the stock to go up to be worth anything. So if the stock price increases ten percent, that would be $420M (120-110) * 42M shares. Still seems like an awful lot.
That's actually not quite how it works: "The options awarded had a per-share exercise price equal to the fair market value of our Class B common stock on the applicable grant date"
Common stock is usually way less expensive than preferred, so while currently the company may be 'valued' at $110 per share, the common stock is probably in the $30s or $40s.
He's likely already up $2B on the stock options (pending vesting), assuming the company does IPO at $47B and all common stock converts at the $110 valuation.
Personally I think this is unheard of -- anyone else know of examples of CEO compensation like this prior to an IPO?
That's not how option valuation works. They're worth the difference of their strike price to the price of the underlying intrinsically. So if his strike is $110 (which it's not for reasons others have pointed out - he was issued options on common stock), he gets the appreciation of the stock after IPO once he exercises. If the stock plummets after IPO, his options will expire worthless. Though they are probably LEAPs, and it's weird to denominate options per-share like that. Normally contracts are for 100 shares and it always confuses me the way companies award options.
It's fulfilling to do that, but all successful startups go through a phase where they become more professional and hire a lot of experienced leaders. The culture the 'old' team worked to create very quickly gets diluted and replaced. Not necessarily for worse, or for bad reasons, but it's a reality that a lot of early employees find challenging.

Isn't this sort of security something we wish we didn't have to learn? And for people who don't take the time maybe it's best to let a third-party handle it.

Absolutely. Time spent on your auth scheme is time you're not spending on building your product. (And half-assing your auth scheme generally comes back to bite people.)
That said, outsourcing it to a centralized provider may not be the best idea for business, user, or security reasons. So it's a balance.
Of course, I'm biased: I work on the Persona team at Mozilla, where we're trying to build a simple, secure, fully decentralized, and open source authentication system that fits that niche rather nicely, but the points above stand: you have to figure out the opportunity cost of your chosen solution. There's no universal answer.
100% agree with you. I love the concept of Persona, but it has a serious cold-start problem. If I could implement it and nothing else on my site, I would, but unfortunately the reality today is that most users don't know it.
