As stupid as Alexa is at the moment, and considering she cannot get a lot of simple commands correct, I think the intercom feature will likely blow chunks for the foreseeable future. I think a truly usable intercom system is way beyond the ability of Bezo's Bozos to program. I suspect whatever they provide, it will be highly limited in functionality and prone to failure more often than not. Eventually they might get it right, but I'm not holding my breath until then.
