I really doubt that “/command” will prevail. For developers this is a natural thing, but for most people it is pretty confusing. I suggest you to look on messengers like snapchat and dialogs built entirely on small icons or stickers.
Just like hyperlinks on the Web :) As you know, Hashtags provide a powerful shorthand for hash terminated HTTP URIs which unleash the name->description indirection powers of the “#” indexical.
Anyway, Bots are certainly the next major innovation frontier and hyperlinks (be it as hashtags) will drive the inevitable explosion…
