If this is accurate, this suggests that abiogenesis is easy once one has a stable, watery environment, since it happened twice on Earth.

That was my first thought too. (Assuming the article is correct - all kinds of stuff gets published that doesn't hold up in the longer run.)

One potential conclusion about the Fermi paradox [...]

Remember that time is also big. Suppose that there have been 1000 interstellar civilizations in our galaxy during the past 5 billion years, and that each one lasted a million years before collapsing. How many would be active right now?

Frankly, I don't consider it a paradox at all. We've explored approximately 0% of our galaxy and found nothing. That doesn't tell us much.

The stock price was inflated to start with, due to speculation. Elon was just taking advantage of the situation. "Oh, you want to buy a tiny fraction of my company at way more than it's worth? Sure. I can use an infusion of liquidity." What's bonkers is that if you sell 1% of your company for $20 billion, the talking heads then pretend the whole company is worth two trillion. Who would actually buy SpaceX for two trillion dollars if Elon wanted to sell it? But they call him a trillionaire. He's only worth the net present (discounted) value of all future earnings of his companies. Yes, that's a lot of money, but look at how much these companies make and do the math.
