Me creating a self-driving car will take away revenue from drivers. However the rest of society will gain much more than the loss that the drivers suffers. On net humanity is better off.

This is true when the computer replaced secretaries, when cars replaced the horse, when planes replaced the boats, internet replaced fax and phone calls, etc. Overall the quality of life of everyone improved even if a select few suffered each time progress was made, making even fewer rich, but everyone else better off.

You create wealth by providing value to others, value that exceeds the competition you have displaced. That's why wealth creation is a positive sum game.

I think it'd be more accurate to say "play the value creation game" then. The author specifically references wealth accumulation (ie. the accumulation of assets)
