It's interesting we view Email and Chat so differently. Some companies run on chat (e.g. Slack), while most companies run on email.
Emails are so similar to Chat, except we're used to writing in long-form, and we're not expecting sub-minute replies.
Maybe emails are going to be the new chat?
I've been experimenting with "email-like" interfaces (that encourage you to write more / specify more), take longer to get back to you, and go out to LLMs. I think this works well for tools like Deep Research where you expect them to take minutes to hours.
