I don't see how you equate serverless with another person's computer. Cloud computing is another person's computer, sure, but there's not really a local equivalent for something like AWS Lambda as far as I know. Having an API call or trigger that pops a machine into existence, runs the code, and terminates the machine in a couple hundred milliseconds isn't something I've ever really seen used outside of clouds environments.
