It’ll be interesting to see how Apple gets back into this race. Amazon has executed brilliantly but it was Apple who initially opened people’s eyes up to the potential of voice UI via Siri and HomeKit. Apple will need to loosen their requirements a bit and maybe allow voice authentication as a means to unlock commands. Currently the requirement to use a passcode or fingerprint to unlock whenever I say “Hey Siri, turn on my light” is cumbersome and defeats the purpose of an ever ready voice activated computer in the home. Google has a lot of promise though they need to step on the gas with respect to building out the ecosystem. Also I’m intrigued by how they’ll handle the equivalent to Skills. IFTTT is a stopgap for home automation (for ex. works like a champ with the Securifi router) but it’s not a mainstream solution. Fun times ahead.
