I imagine what is impossible at Valve is keeping people working on projects that the employees have lost interest in. I suspect this is what is happening in CS2. As a player, I can feel the lack of interest in the well-being of the game, the lack of skilled talent working on the fundamentals. Even though this game has made Valve more money than any other game on its platform, they just don't support it enough probably because it just doesn't excite the employees much anymore.
