I'm more shallow than you gave me credit.
Nah, I just think too much.
Newton wrote twice as much about Alchemy than Physics. We can regret the fact that he wasted so much time on immortality and gold transmutation, or may be.. Newton would not have found anything in Physics if he wasn't so obsessed with Alchemy.
I think the counter argument you're trying to make, and what would actually be the counter argument to the article I shared, is that there are more "dead ends" in science than "discoveries" but we don't always know where paths will lead unless we decide to explore them.
In regards to Alchemy in particular, I sometimes wonder if that's something we could consider re exploring, what with a more developed knowledge of math and physics and fusion and fission and such.
So I guess, let's enjoy our video game and comics readings, it might bear fruits we wont reach otherwise
I'm not saying we shouldn't, but I also think we should be more careful to the extent that we pursue these things and try to better understand how they can affect us.
