Servlus - What's Temporal?

Temporal is a work flow engine where you can write long running processesso. It's not immediately obvious why that's a big do at all, but if you look at the jobs to be done of a cloud. And i've been very inspired by it ever since i heard about psychic from the indi hackers podcast. I think servelus may be an easier bridge into building back ends for front end developers. We're still trying to figure outike how to explain what it is.
