A serverless language doesn't really explain what it is, I mean JS, Python, Java etc.. all run in serverless environments.
But after reading more it seems similar to Erlang, as each function can be deployed to other systems and invoked as if it were a local function... <- this is what you want to emphasise.
I would suggest adding a graphical flow chart on how this works (maybe like this https://i.imgur.com/fJHyJni.png). Perhaps a comparison of how regular programs invoke functions, compared to how Teal invokes functions (showing scalability and parallel computing).

This is not a good reason. If you want people to learn a random language, you need to demonstrate the reasons why it's better! At first glance it seems crazy to have no interoperability with another language/package manager.
Anyway, sorry if I sound critical, I think there's real potential in this idea and am excited to see more development for Teal!
