The ones that make the most are normally the quietest lol they learned to drown out the naysayers and instead focus on what really matters the data and the drive which are building these platforms. Granted to say it's not to late to get involved but acting now today instead of waiting is what will hold most people up. Same thing in the marketing world. So many people read and learn or don't and never take any action then just complain about those who did do something.
