You have no idea who you're talking to.

I do hope your small-mindedness does work out for you, though history has shown being actively hostile to innovation is not a great way to survive rapidly changing environments.

Edit: it seems that I accidentally used a phrase that triggers people. "You have no idea who you're talking to" doesn't mean I am some important hotshot, I just meant it literally. This dude is personally attacking me and my thoughts and he doesn't know who I am at all. It is mean and I am not here to be treated like that.
