I think some of that is a certain group of people will do anything to play with the new shiny stuff. In my org it's cloud and now GPU.
The cloud stuff is extremely expensive and doesn't work any better than our existing solutions. Like a commentator said below, it's insidious as your entire organization later becomes dependent on that. If you buy a cloud solution, you're also stuck with the vendor deciding to double the cost of the product once you're locked in.
The GPU stuff is annoying as all of our needs are fine with normal CPU workloads today. There are no performance issues, so again...what's the point? Well... somebody wants to play with GPUs I guess.
Resume-driven development. It's probably pretty much always been a thing.
