The big problem with Jupiter is its particularly intense magnetic field and Van Allen radiation belt. It is going to be too dangerous to approach without a breakthrough in radiation shielding for a long time yet. On the other hand, once we get fusion, its containment is likely to be magnetic, which may be adaptable to shielding.
