That's a very unreasonable point of view. Sure, it's true that in the past 200 years we've had an explosion of technological progress but there's absolutely no reason to assume that it's possible to continue it for an infinite amount of time. It's rather more likely that over time we'll discover the lines that separate "hard but possible" from "theoretically impossible given the physics of this universe". The only real question is when that will happen for any given area of technology. Asserting that technology will just continue to improve and advance forever simply makes you sound like a stock-market broker in 2007.
