Don't get me wrong, I get the theory, I've just observed very differently in my career. No, I'm not suggesting people stop trying to improve tools, I use very good tools every day ... I'm saying ... I give up, theirs no way to not offend people in these discussions hehe, this is why developers don't like to talk about this stuff ...
It's just, a tool. (this is my own opinion of course!) tools don't make games, people do.
FYI - tools are usually made to speed things up, to save time, to save money (and often peoples sanity) they might, depending on the tool in question, make the game better, but not always.
