Just as it got easier to use email, it will be easier to use Bitcoin as people invest in it and become more familiar with it.
While Google has given away pretty much everything it has to offer - from search and maps to email and apps - this has always been part of its greater revenue model: the pennies per placement it gets for seeding the entire Google universe of search and services with ever more targeted advertising.
Email will probably be around for many decades to come. It's hard to say what will happen 20 years from now, but email has been around for decades, and it will likely be around for decades more.

When I go a stretch without tweeting, I will occasionally get an email from my mom, checking in. I always find this amusing but also gratifying: Thanks to Twitter, I can keep in touch with my parents and let them in on what I'm doing in a way that even the regular phone calls of a doting daughter can't do.
