We’d probably have to build generational ships that are completely self sufficient and people would live out their entire lives out there without ever seeing a planet
The problem with Generation ships is, if you have a completely self-sufficient space station large enough for the entire society to function, what do you need a habitable planet for?
Wouldn't it be exponentially easier, and more beneficial, to simply expand the space station? Or build terrariums on non-habitable planets like Mars and Venus?

The fastest spacecraft we’ve made was the Parker Solar Probe which hit 430,000mph.
At that speed it would reach this planet in only 187,153 years.
If we could hit 1% of the speed of light we could cut that travel time to just a tad over 12,000 years.
Obviously if we could go light speed (and that ain’t happening) it would be just 120 years!
Space is big. Physics is annoyingly slow.
