Don't forget that more engineers can increase wages too. You seem to be stuck in a bit of a simplistic lump of labour idea about supply, demand and salaries.
More engineers means there are more companies that can grow, which increases opportunities for integration and building on top of. Think of engineers as more like fuel for a fire: the world isn't sufficiently automated, and the way we automate it is by applying engineers to the problem. The more we throw at it, the hotter it can burn; and the rewards depend on the value of the thing being automated, not mere supply and demand.
If we only had one engineer, they would not be worth the billions of amappgoosoft put together. It's very far from a zero sum game.
