The lesson here is that the things that are designed to help or entertain us have unintended consequences. Technology can make life easier in a lot of ways, but it also has the potential to cause harm--usually in ways we've never considered.

If nothing else, Pichai's warning should cause everyone to stop and consider the lessons learned from previous forces with the same potential for good--and destruction.
