Some people just don't know any better or have starlight in their eyes and they manage to convince the business they need it. No brakes, no caution, no reflection on if they reallly need it. They just want it cause it is fashionable. Then when they eventually realize they are deep in a hole or it that it was the incorrect solution to their problem, then it becomes everyone else's fault (aws's fault, cloud computing industry blah blah blah) and they write blog posts about how terrible everything is, all while making businesses and other people trust us less and less each year. But that one clown not "using the right tool for the job" will never admit it or they disappear or move onto the next fad (he's probably a crypto bro now after implementing a piss poor chatbot somewhere).

Measure twice, cut once. Fail fast is load of nonsense and burns a lot of money for no good reason.
