Science is not at all random. Seldom requires practical uses (even if eurekas are a shot at it). Perfectly linear output.
Not so much real life.
Not sure what is your real point here. Are you saying that science in reality is not at all random or just right about the contrary ?
I mean, science is random, technics are more linear. You can't obtain a haut fourneau in the first try, you have to make camp fires first and even "find" fire. The degrees of temperature here are, here, linear. I would say. The principles of the steam machine were invented in Antiquity. But, we didn't have the tools to build it.
And yet, technics, while influenced by pure science, influence science on its turn. We have no clue if the E.T. discovered the same things as us, or in the same order. We discovered the transistor, that revolutionized the society, but if there was something similar, more powerful and more simple at the same time ?
We have known the cold war, and the WWIII is at our door, but was this the case for the E.T. ? Did they get nuclear fission that early ? Didn't we tangle the brushes by highjacking some E.T. (or futuristic) technologies so now we don't even know where to search ? (we are, in spite of our increadible tech, at point 0 as to traveling into other stars reasonably, which is the only, the ONLY thing that gives importance to science : even if we could get all somewhat immortal, there would be no more space for every family, even if we could resurrect people from the past, and the present accidents, there wouldn't be enough space, etc. Not to mention one of the greatest, if not biologically programmed, joy of the life which is to reproduce and multiplicate, so basically one given species is not very good at preserving itself, it mutates and becomes something else or get extincted for other species to grow. We are one "intelligent" species. Or at least we see the void between the moments. That makes each of us go in whatever direction. Will this chaos lead us to a quicker extinction, or will a handful of us save all the other ones ? As to a species ? Physically ? Or is there an ascension of the Soul that a lot of religions try to answer ? See, there are deep connexions at science with religion. The only problem I have with them, is that they need belief, not explanations as I did simply above. If anything, religions have been invented by E.T. that felt so superior that they couldn't believe that simple explanations were understandable by us, at least in Antiquity. Unless we need to ignore this apple in order to do so ? You can't sleep willingly, or at least not with a certain level of it. In a moment of trouble, I've asked God once to give me sleep. It worked. Even earlier, I've asked Satan. It didn't work. Sorry Satan, but we don't have a deal here. Anyway, I had way enough sorcery to deal with.)
Oops, I did it again. Sorry for that !
