i think the slack side is easy. I think an AI-optimized email communication channel is a long ways off. I spent weeks throwing things at my monitor figuring out reliable ways to wire DNS+SES+SNS+Lambda+Webhooks+API+Datastore+Async Workers so that everything would "just work" with a few lines of humanlayer sdk.
And what we build still only serves a small subset of use cases (e.g. to support attachments there's a whole other layer of MIMEtype management and routing to put things in S3 and permission them properly)
