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.
