I’d love to try it if they didn’t tie the language to their hosting service. I understand the necessity of the coupling but until someone can start a competing hosting company with the same language, it’s not something I’m interested in.

Huh, Dark looks pretty similar to what I'm doing, albeit significantly more work since they went and developed a whole language and editor. If you're not averse to Clojure, give this a look: https://github.com/acgollapalli/dataworks

Totally reasonable. I feel the same way, but there are a lot of people who just want something up and running and are happy to accept vendor lock-in risks. I'm sure they'll get there eventually.

I agree here. It's really exciting to have a platform where the friction of releases is totally removed. I'm excited to see where they end up with this product.
