Very true. I personally think smartphone’s search bar will prevail. Since deep linking is already in place and machine learning algorithms implemented properly will help deliver the content we need without installing any apps, just typing keywords is enough. Searching for apps, downloading it and finally using it. We would be skipping first 2 steps. But for this, every developers should submit their app like creations to apple or google in order to be searchable. I’m sure this has already been thought and being worked on.
