If Russell counts as a major Philosopher, then in his opinion (towards the end of the introduction to the *Tractatus*), Wittgenstein solved the problems he set out to solve; but he explicitly notes that there remains questions of 'life' that are untouched, and implicitly more important questions ie ethics, politics and power so on.

His followers are strictly involved always in interpreting his philosophy; but also moving it on in different directions - hence the room for disagreements is plentiful.

Personally, I think his lasting legacy will be in mathematics/mathematical logic with Model Theory which is a mathematical interpretation of his theory. As also one philosopher told me, his influence in analytic philosopgy and in wider philosophy is waning. People are beginning to realise as Russell noted above that logical atomism leaves the questions of life untouched.
