EEEEEEEEEH, WRONG.

Heavy asset producing investments always get simplified with the improvement of technology, JUST LIKE OUR OLD COMPUTERS, WE LOVED THEM SO MUCH, WE MADE THEM EASY.

Same for computer software, and thanks to Blizzard Unifying the need for detailed games, there will always be 11million+ people in demand of this software. Which brings us to the question, where do we get this software when there is no Blizzard?

Innovation, invention will produce simplifications to software design and production. Dont believe me? Go read about the "Hero Engine"
How many games were made on the Unreal Engine, and the Half-life engine.

Just, take a history on developing sciences class, in any tech study, and re-think your hypothesis.
