Is SEO dying day by day? if Yes then what will be next option? if Not then how?

Previously Seo was about only keywords, but now it has changed completely because of their latest Algorithm like "Hummingbird" "Brain Rank" which uses semantic search - a data searching technique.

So Day by Day Search Engines Algorithm becoming advanced. so it can't die instead of dying it will be into more in Machine Learning which will understand the user behaviour on the website. 

I don't think SEO is dying. Infact, I think it is even more important to optimize your websites for search engines. However, we also have to look at other areas for growth. One I see is social videos, predicted to be 80% of online interactions by 2020. 

SEO will die when search engines die. I have been hearing this since 5 years but SEO is working and getting mature with the span of time. I have seen increase in SEO clients in 2 years and they are getting good business as well. 

Do you think SEO is dying? If yes why clients are reaching us for SEO? I hope this will clear the confusion.
