> The only philosophers of that kind that produced an advancement in terms of stuff being consumed are the ones who did it all inside their heads and the only expense they needed was paper and pen (Einstein, Feynman, Bohn, Maxwell..)

This argument -- which is brought up in every sophomoric conversation about the nature of science -- is extremely poor and unjustified. Of course Einstein, Feynman, Bohn and Maxwell relied on observations. Their theories fit the data that was collected before them. If you ever want to give the next Einstein a chance to build an even more useful theory, you need to observe more data. Period. This is how science works, you observe the world, you build a model that predicts it, rinse and repeat. There is no such thing as "purely pen and paper" in science and it categorically can never be. The idea that Einstein came to relativity through pure reasoning is silly, his theory was formed to explain observations that cannot be predicted by other models. Of course it involved tons of pure reasoning and mathematics, but the basis was only empirical observations.
