> Are you confident that will be the case in 5-10 years?

Yes, I am. I am very confident that general purpose digital computers will never be more efficient then human minds in generating moderately complex code.

Why am I so confident... Well, it has been over 10 years since AlphaGo beat top go player Lee Sedol. AlphaGo was able to beat the a world class go player by doing several thousands orders of magnitude more computations then Lee Sedol, and it did so by spending several orders of magnitude more energy then the top human go player. Today, over 10 years later, the top go machines are able to beat world class go players much easier, but still do so using the exact same strategy of outcomputing the humans with thousands of orders of magnitude more computations, and spending orders of magnitudes more energy.

Things did not change in the past 10 years, I see no reason why it should change 10 years from now.
