Someone should really attack SFDC from the "malleable Business OS" side of things. Unfrotunately everyone seems to attack it from the CRM side of things and lose the plot a bit.
Def agree that "have the thing I just came up with running in some environment that is sharable" is still a pretty gnarly problem, and LLM stuff doesn't... I don't think they've really made much progress on it.
At one point someone really needs to make an easy to manage box metaphor for all the stuff. It's not Docker. Google scripts is almost there but you really want to have the database be a thing you can drag and drop as well (SQLite people: get excited!)
Dropbox for business apps. If anyone runs with this at least send me an email thanking you for the metaphor.
