"for funsies" probably isn't that far off. Because the process is more like someone gets interested in something at some point. Then at that point +~1-6 months someone raises a problem and some senior dev gets stuck on the idea that the awesome thing they read about can solve it. Then before you know it whatever tool they want to use has more bells and whistles than the average mars lander and does everything short of curing cancer.

There's rarely any good correlation between the problem and the solution. That gap can just be bridged by buzzwords. The true correlation is usually between the solution and whatever the most senior dev on the team thinks is shiniest at the moment.
