Virtual Reality, Artificial Intelligence, and android skills may even be how terrestrial kids could be raised in a not inconceivable future. Hell, just send/build androids...

The first step is rocket fuel production somewhere closer to orbit.
The second step is fusion technology
The third step is fusion powered factories making anti-matter
The forth step is a probe
The fifth step is an automatic factory/station to receive the visitors
The sixth step is sending the colonisers.

So we need much better automation, as well as tons of cheap energy ...and possibly some new definitions as what constitutes a representation of human/solar society.
