Some overall thoughts from me:

• Personally not a fan of how "hype" the language in the post is; it reads as far too much marketing speak to me, and in my opinion a more reserved but focused tone on the technical details might leave a better impression. As it currently is, it reads like a blog post a startup would post about their product, which isn't necessarily a bad thing in and of itself, but I don't know if that's the kind of tone we're aiming for in these blogs posts 🤔
• It would be better if the example was a concrete example and not a dummy example. This relates to the previous comment too; if this feature is being hyped so much, at least a concrete example should be provided instead of a template that leaves the actual "async work" up to the imagination of the reader
• Perhaps we should mention how async UDFs differ from table sources; it might seem obvious, but some of the use cases for async UDFs mentioned here (e.g. Fetch data from cloud object storage on demand) sounds like something you'd achieve via querying tables rather than something you'd do in an async UDF

These are just my personal opinions, feel free to consult other opinions which might differ from mine 👍
