50 years after a self-improving AI is released into the wild, I don't expect Venus and Mars to be in their present orbits. I expect that they would be gradually moving towards being in the same orbit that the Earth is moving towards (or is already established in) 120 degrees apart, propelled by a rocket which uses large reflectors in space to heat portion of the surface of the planet, which is then forced to jet in the desired vector at escape velocity. ETA: That would mean the removal of three objects from the list of planets of Sol.

I think it will only be a few hundred years after FAI before interplanetary travel requires routine 'take your shoes off' type of screening.
