As I noted, Google makes great products including gmail. My point was that with gmail being free and good enough, there is nobody to compete with gmail. In 2016, nobody will start an email company even though there are lots of advancements that can be made.
I don't agree with this. Google competes against Gmail with Inbox (a very advanced email product.) I also see people paying for Fastmail and some of the encrypted email products. Yahoo and Microsoft have also been improving their email services. I always like to see more competition, though.
