You might be entirely right, but the universe is a big place. Estimates of the number of stars (called Sagan's Number[1]) are on the order of the 3 x 10^23 (300 sextillion[2]). Even if only a tiny fraction of a percent of them had worlds with intelligent life, there'd be a lot of it out there. The bad news, though, is that it's still hard to travel, or even send transmissions, so it's just as likely we're doomed to stay lonely. (I tend to share your optimism about the odds of other intelligent life being good-natured; we've come a long way in the last 2,000 years, by the time we're out in the stars, I'd like to think we'd all be Bodhisattvas). 1: https://en.wiktionary.org/wiki/Sagan%27s_number https://en.wiktionary.org/wiki/Sagan%27s_number 2: https://www.npr.org/sections/thetwo-way/2010/12/01/131730552/-trillions-of-earths-could-be-orbiting-300-sextillion-stars https://www.npr.org/sections/thetwo-way/2010/12/01/131730552...
