I'd argue it would be pretty uninteresting to follow Oumuamua where it's going. It was traveling at 0.001% c and the nearest star is 4 light years away, so even if it was aimed directly at that star system, it would take 400,000 years to get there. Oumuamua is going to spend a LONG time cruising in the darkness.
