Underdelivery is par for literally every human institution on earth. The federal government underdelivers. Corporations by default underdeliver. Grad students underdeliver. Football teams underdeliver. Every single institution on earth more ambitious than lawncare services makes lofty ambitious goals and then achieve maybe 20% of them. Musk is the same, but the difference is that his 20% are orders of magnitude more ambitious than anyone else, so 20% delivery is still world-changing.
