It's all about scalability. With serverless, you can have your functions running on machines all over the world, at the network edge closest to your end user. You can scale from minimal to maximal without any intervention whatsoever, and only for the hot parts of your code. Deployment is even more refined than with containers.

I sincerely hope to get to work with this stuff soon; no use case for me at present.

You can do that with containers and VMs too. Potentially with fewer worries about cold start latency (at least with Lambda).

Fargate is an interesting sort of middle ground.
