I don't know how you can say HFT is dead. First of all, what is HFT? No one seems to be able to agree on a definition. While some strategies that trade at high frequencies have certainly been squeezed out of existence (and sometimes whole firms), others continue to do well.
I think the ones that strictly rely on speed and being second place means not making money. Then yeah, those strategies are a waste of time and dead to everyone except the firms that can afford to be the fastest. Additionally, any firm using strategies profiting from market structure loopholes will die sooner or later as well. The trick is for them to keep finding new loop holes.
