An object can accelerate arbitrarily, but in any reference frame it will never be traveling faster than c.

Of course, it won't collapse into a black hole, but the amount of energy needed to accelerate further will increase asymptotically.

That is actually false from the frame of the traveler. Using constant acceleration, the traveler will observe constant energy usage. Then length contraction will guarantee that you can reach speeds arbitrarily close to speed of light( and also any location in the universe ) in about ~50 years with 1G acceleration.

Yes, but when do you get there? In 50 years in your time, but it may be a few billion years later in their time...

I believe that is the point. Even more time for the stationary computer to finish the calculation.

Note the Scott has made a correction in the comments.
