Relevant war story: I was one of the engineers who initially started looking at GPGPU computing at one of my former employers. This was circa 2007 and people were getting really excited thanks largely to NVIDIA's hype machine. 2007 BTW, was when the first Teslas were making their way into the wild.

I was part of a group that developed signal processing algorithms and my boss's boss pulled me aside and asked me what we ought to do about this stuff. I told him that there are a few applications where this works very well, but it's pretty niche overall and we shouldn't do more than what we'd already done. He was a bit surprised because he thought I'd be one of the kool-aid drinkers given how much I knew about and liked playing with the tech. But he deferred to my judgement.

It turned out to be one of the most significant conversations I've had. I was still a junior engineer fresh out of college, but my bosses realized that I could be trusted put aside naive enthusiasm about the tech and make cool-headed decisions about what was strategically important. And I learned to trust my intuition about what was useful and what was just hype.
