You just made me think about a few issues: 1. wouldn't these five be a cute quasi monopoly? (is pentapoly a word?) 2. isn't it brilliant how "they" - including many others, like Musk - make a big fuss about AI that is mostly already open and published, while what we should worry about is data? 3. is there any hope for an open society when most of us nerds - who are supposed to be all rebellious, undergroundy, security aware etc - with a lot of power to build the future can't wait to run into the arms of these big guys? We could use more @dhh type opinions.
