It comes across, in the context of the comment you replied to, as incredibly dismissive. If you can't see that, I can't make you see it.

It also seems to imply that the rest of the world would tell you to stop working on your supercomputer and go deliver rice in Africa or something. This actually is elitist and condescending, as it assumes that just because people are starving today they would be unable to understand the value of your work. You should give the rest of the world more credit. That's the elitism.
