Think tank is a buzzword therefore a think tank couldnt have possibly invented buzzwords.

Aside from that tautology in my opinion and in many definitions of think tank it's private nonprofits that are distinct from the traditional academic read watch and funding process. Looking at your MIT think tank they are assembling a group of thinkiners distinct from the traditional MIT research process. Your examples appear to be regular academic research creating buZwords

In your posts it appears that buzzwords are started and MIT and Carnegie Melon which are both schools and therefore not think tanks. If think tank just means anywhere that research takes place then you have created a tautology of your own and the debate is moot.
