Fortunately, I've neverencountered that. But still, I can see the usefulness of a guaranteed globally unique UUID, at least for certain purposes. However, a service to add numbers baffles me. The operations needed to create, send, receive and check the message are so much more complex than addition...

I must say, I did experience some lousy tech+sales leadership in one company, which was indeed the biggest I ever worked at. A decent product with a well understood scope was completely scrapped and rewritten. Some team spent more than a year on the (waterfall) design of the new system, which was then scrapped too. When I joined, there was an 8 man team for just the message bus for the new new system. Which didn't even work correctly. The whole was flexible, but in nearly every other aspect inferior to the original product. And it needed much heavier hardware.
