Oddbean new post about login | logout I don't agree with that. In just 100 years, we went from using horses to sending a person to the moon. Given a thousand more years, we could become an intergalactic species, if not sooner. It's a very short period of time in terms of universe. Agree, there are most probably aliens out there, I doubt they would crash on Earth if they possess the technology to travel between galaxies.
