Correct. When Tensorflow came out, it seemed that there was already too many good alternatives (Theano, Caffe, Torch). When Chrome came out, Firefox, Safari and the latest version of IE also seemed decent options.
A desktop browser? Made by Google?! In an environment where people have celebratory launch parties for Firefox??
Of course, the business goals made sense, but I don't think anyone guessed it would overtake the market share so effortlessly.
