Why so fast? Why not say, 0.001C to 0.01C? Generational ships are a valid alternative here, especially if humans happen to be very long lived (given that you have "automata" remaking stuff without human input, this wouldn't be much of a stretch technology-wise).
just use MS Excel... 1G = 9,8 m/s².at the end of the first second, the speed is 9,8m/sat the end of the second second, the speed is 19,6 m/son another column, translate that speed to km/s
1.261×10^11 grams

Pretty good waste of time and money there...

Pretty good waste of time and money there... If you're racing to get somewhere first, then just send a payload of a few grams of those "automata" at high speed and forget the rest. There's a vast energy cost to moving a significant fraction of the speed of light. Else, if you just want to get there and aren't worried about being first, then the slower speed is much more affordable.

So any travel that takes "generations" is quite useless imho.

And what does happen to my generational ship, if someone gets there first? Well, if I arrive within a few centuries to a few millennia, there's still probably a lot of good real estate to choose from.

The asteroids look pretty good, but they for the most part have even lower light intensity than Mars
