There's a new assistant in town. Watchout Siri and cortana

Saw the google live stream,
pixel phone made the most hype and they made a huge deal about google assistant, router and daydream viewer.

One thing what android users wanted for a long time is google now to be more interactive . now it looks like their dreams might come true. But How does it stacks up against the competition?

first of all they did a pretty good job with the UI (judging by the demo).  its, in a lots of ways similar to siri or cortana but so much better

it has contextual search built in, so it knows whats on your screen when you ask a questions. that's a huge plus point that gives google assistant an edge over cortana and siri

more over it uses google's knowledge graph, image and voice recognition along with translate. which makes it more natural and accurate in showing results . It can even show results from other websites which google itself doesn't have so it gives answers most of the time instead of prompting to do web search on it (like current generation virtual assistants

So what happens to now on tap?
It's still accessible by long pressing which triggers assistant but then later swiping up the screen will tell information based on what's the context of your screen. So there's just one more action to access it

what happens to the google assistant that's built into allo app?
Nothing can be said as if for now but it seems like it's gonna stay there. Note that it's still labeled as "preview edition" so it might change a bit

what happens to google now?
I don't think it will change, maybe a few UI changes and but they'll keep it that way so there will be relevant cards there. kinda like iOS widgets

what about older generation devices.
Google assistant is a very big deal. They said it is baked into OS so devices that have Nougat 7.1 will only run it. so it will come with an OS update to 7.0 like now on tap/google now was...

i hope it comes to devices with marshmallow as an OS update because distribution numbers for Android suck and adoption rate is slower than my grandma.

NOTE : THIS IS FIRST IMPRESSION and thoughts NOT A REVIEW
