> IBM is generally considered the leader

You must not talk to competent people. IBM is very experienced at this grift. I remember when I used to go to conferences in a different field and IBM would announce "state of the art" results that were very obviously done by cheating (making an ensemble model and tuning the weights on the test set). Everyone doing real work would ignore them, and then they'd go sell to clueless midcap companies on the basis of that announcement.
