There is still a lively academic community and major progress! Check out CMU's no limit results [1]. (I realize articles like this have to pick some angles to make it interesting, but it was weird to see only dated research mentioned.)
But if you are rooting against the machines, don't worry: it is almost certainly impossible to calculate a full equilibrium policy for no limit multiplayer, so we will instead be debating over the virtues of various types of imperfection for a long time. And even if an Oracle gave us convenient access to equilibrium strategy, it would still not be the optimum at a table full of imperfect players. Your poker game is safe for a while!
