Around 2016, the term "serverless functions" started to take off in the tech industry. In short order, it was presented as the undeniable future of infrastructure.

I’m thinking more about being able to run your entire environment locally. We use GCP and we have a combination of appengine, cloud run and cloud functions tied together with api requests and pubsub. The cloud functions are the main bit missing from our local environment as we’ve not been able to spend the time to set it up yet.
