>Especially to the level of sacrifice they were willing to take for the cause.
We have no idea that they were sacrificing anything personally. The packages Microsoft offered for people who separated may have been much more generous than what they were currently sitting on. Sure, Altman is a good leader, but Microsoft also has deep pockets. When you see some of the top brass at the company already make the move and you know they're willing to pay to bring you over as well, we're not talking about a huge risk here. If anything, staying with what at the time looked like a sinking ship might have been a much larger sacrifice.
That's not true, Capital would still accumulate returns higher than the cost of inventory plus wages, the return would just be the same 'everywhere', and you'd have a perfect market alpha for all stocks, whether it be 1, 2, 5, or 10%. Even perfectly rational markets do not establish socialism overnight. Now maybe you could argue under a Marxist lens that exploitation would be more 'visible', causing socialism to arrive out of social rebellion faster, but that's really besides the point.
What would cease to exist would simply be speculation and arbitrage. Since all prices are perfect, you simply wouldn't be able to make more (or even less, for that matter) money than the return on capital everyone gets by buying and selling shares quickly.
I don't think it's so much about the timidity of the driver, it's the effect on driving slow has on people behind you. Driving below the speed limit increases the amount of drivers who need to do overtaking, which are moments substantially more dangerous than just driving straight. If it weren't for forcing other people to overtake I don't think we'd really care, even if it was a sign of timidity.
Very common to see older people drive slow on the highway because going 100KM/h seems scary to them. This is, of course, absurd, since driving 80KM/hs on a 100KM/h road causes way more moments for bad things to happen because you're forcing everyone to merge into the speed lane, including trucks with bigger blind spots, rather then only the drivers choosing to go above the speed limit. If you do this you should absolutely be fined, and that's not because it's a good metric for timidity (which I agree can be bad for drivers in general), but rather that the action itself causes harm.
This is actually true, but I still use PayPal probably 10-20 times a year and I haven't logged into their site for probably 2-3 years, at least whenever I last had to update my payment cards.
The site is suboptimal, it's probably not a great company and I have no idea if they're charging me anything - but the one-tap purchase system just works, and that's all I need. There are other great options in Klarna and similar, but even they give me too many options to coax me into paying later so I inadvertently pay fees. PayPal literally just withdraws from whichever card has sufficient funds at the time, has worked exactly as stated for over a decade, so I really have no incentive to investigate alternatives (especially for sites where my PayPal is already setup, like Steam).
