I am going to ask a very direct question and only because I am curious.

Why do you care? Why would you spend your own money to a multi trillion dollar company so that they win their own "war" against another multi trillion dollar company?

Please don't get me wrong, I know the question can seem a bit negative, I am really just curious.

No, it's a fair question. The answer: I believe(d) in Demis Hassabis's vision of AI

Although, I think saying 'wanted them to win' was not accurate. More like, I stuck with them hoping it will get better, and it did get better in many ways, coding was not one of them.
