Quitting coal mining in exchange for lithium mining? That’s like saying an addict is healthy because he quit heroin in exchange for being hooked on fentanyl.
CO2 in the air is damaging all life on earth, while a lithium mine at most damages the local area around the mine. It's probably much better to have a few local "dead" spots than a complete planet out of whack.
And as a sibling comment said, lithium can be recycled.
CO2, whether from fossil fuel combustion or respiration (e.g. part of your and my exhaled breath, day and night) becomes plant tissue. Land plants, algae in the oceans, the herbivorous content of your salad, the flowers in your garden, etc.
Yeah, well, I expressed myself clumsy. CO2 in itself is not bad, but the global warming effect caused by too much and unnatural CO2 in the atmosphere is bad. And that global warming effect slowly wreaks havoc with natures balance and long-term kills life on earth as we know it.
“However, this point of view has been increasingly questioned in recent decades, and a few trigonometric proofs of Pythagoras have made the rounds since then. Claims in the media that Johnson and Jackson’s proof is the first trigonometric proof of Pythagoras are overblown, but their proof could well be the most beautiful and simplest trigonometric proof we have seen to date”
my understanding from this part is that their general approach is not new (though certainly astonishing for HS students) but their proof is novel.
That’s the problem with Slack — too easy to switch to equivalent or superior alternatives. I suspect this issue will continue to weigh on their stock price.
? Would you want a majority of your wealth tied to a business you used to work at? Or would you rather use it towards things you are actively working on?
I want it tied to a good business. I’d tie my wealth to Google (when they were the same age as Uber), whether I’m the CEO there or not. It doesn’t matter because it’s a great business. If Travis is selling then he agrees it’s a bad business.
