What will be the biggest next revolution in technology?

Anonymous
I still see no new real revolution for years. We all use the smartphones and they always have the almost same features with each other.

I purchased my phone 5 years ago, and I don't feel a need to change it with a 2020 phone because all features are almost same. Just because being able to use browser and YouTube and some apps, I won't purchase a new phone again.
