Google Pixel phone, is the default interfaee for Google's first designed phone.
The assistant is also available from the Google Allo application for those who dont have the £650 to buy Google's latest phone.
The idea is that instead of just searching Google you have a conversation with the assistant. The conversation understands context so after asking how long is the Golden Gate Bridge you can follow it up with "How do I get there?". Google assistant is supposed to work out that what you want is directions to the previously mentioned query. Context.
Behind all this is the idea of "bots". Robotic like beings that live on the internet and respond rather like call centre staff. You might say this is an extension of search or the direction that customer service is heading.
However it's not just Google. Microsoft is also putting money into the bots too.
Skype Preview app now has a bots section where you can interact with freewheeling bots. The Skyscanner bot allows you to book a flight just by talking to the bot. You can order a pizza, play blackjack and lots more.
Both Microsoft and Google think the future is "bots". I am not so sure. It seems to me that to command a bot you have to have a clear idea of what you are doing. Booking flights is sometimes a matter of browsing, looking a different prices, backing up, checking times and much more. I tend to think websites are better.
However in the era of Snapchat and Twitter maybe bots really are the future.
