Wittgenstein rendered further philosophy pointless, even later Wittgenstein really just sets the stage for more empirical studies of visual perception and pragmatic linguistics. Philosophy was very important in Aristotle's day, in Avicenna's day because it was intimately tied with logic and thus how to interpret empirical phenomena. Thanks to the work of thousands of year's of philosophers we now exist at a point where further exploration is not needed.
Discussions of consciousness and qualia should be left for New Age retard who use terms like "quantum consciousness" and talk about the 7 chakras (which is a 19th century western invention and has no connection to the hundreds of potential historical chakras).
An education in philosophy is utterly vital, you can see then when you see the Post-Rationalist community get excited every time they reinvent a concept that Plato, Heraclitus or Kierkegaard already figured out.
I think Information Theory is far more significant to questioning and problem solving than most contemporary philosophy, the ability to determine the entropy in a certain branch of a decision tree or to determine the mutual information of two independent variables is much more useful and important in determining how to go about further empirical study than nebulous questions over metaphysics.
