By far the most important and impressive USP of the S8 willl be their new assistant called Bixby.
The secret to Bixby is the system actually writes it's own code. In contrast
to any other similar system, It is a profound and monumental giant leap
forward compared to Siri, Cortana and Google Now.
Bixby uses a patented exponential self learning system as opposed to the linear programed systems currently used by systems like Siri, Echo and
Cortana. What this means is that the technology in use by Bixby is orders
of magnitude more powerful.
Big mistake stating that Bixby is like Siri, Google Now and Cortana. Bixby
is much much more and much more advanced that these 3.
Siri understands 250 commands at max. Bixby several hundreds of thousands
and potentional an unlimited number because of it's modular and open
design and self learning capabilties.
Unlike other existing AI-based services, Bixby has a sophisticated natural language understanding, machine learning capabilities and strategic partnerships that will enrich a broader service ecosystem.
Strange that so many tech journalists know so little of Bixby.
I love Samsung, I have an S7 myself but after what happened with the Note 7, I would not just buy this phone (s8) right away, I would wait a least a month or two to see if it is safe or not to buy it, but I'm really happy with my S7 right now and I don't think I'd switch that soon..
