TVs, computers, et cetera, are not based on the fact that the Earth is round. Thomas Edison didn't construct the lightbulb and then go, "WELL! It's a good thing the Earth isn't FLAT, because otherwise, this little fucker wouldn't work!" Graham Bell didn't go, "Oh man! I hope the Earth is round like I think it is, otherwise, this telephone would never work!"
Modern inventions have absolutely nothing to do with the Earth being roun, so give it up.
Flat Earth scientists haven't provided us with many valuble inventions, sure, but that's only because there are so few of them, and most aren't dedicated to inventing anything, but more into developing physics and experiments for the flat Earth. I really don't see your point is.
Not to mention, I don't see how "I'd rather believe a science..." has anything to do with which one is correct. All it shows is that you have a preliminary bias for one model over the other, which I'd say is a bad thing.
