Wish we would stop saying "use a cloud service" for everything. People can and do operate their own hardware, manage their own databases, and build and maintain their own application stacks. I don't know how we got to this point of learned helplessness where now we just have to use cloud providers for everything.

It's not learned helplessness to avoid re-inventing the wheel. At the end of the day, the goal is to deliver value to customers, not invent a queueing system, unless your company's product is queueing systems.
