Not sure I understand the use cases. I'm guessing people want to run unsafe nodejs code. Either cloud providers like for lambdas or on personal computer for AI coding? On cloud why is this better than firecracker, firecrack can run any programming language this is just nodejs so already useless for that use case?

For personal computer, people worried about the spin up time of docker? I think that is more of a tooling issue where you spin up one instance and run multiple jobs.

What am I missing? What are actually real use cases where this would be better?
