We’re doomed if we don’t spread out. Staying on earth guarantees destruction by asteroid, super volcano, coronal mass ejection, war, disease, ecological collapse, etc. Settling the solar system is a bit better but still subject to rogue brown dwarfs or black holes, gamma ray bursts, variability of Sol its eventual death. Even settling our local group of stars could end badly with a big enough super nova. Every year we delay expanding into the universe is another light year of distance we may never get back.
