AI and Machine Learning are newer, and probably have plenty of productivity gains to point to, but the thing that comes to mind for me is the amount of CAD and computer analysis that goes into our products these days. You can make a car that lasts twice as long and is more aerodynamic. Musk's rockets use computers for design and algorithms to land. The down stream effect is new satellites with more bandwidth (e.g. Iridium). In the end, a designer can make a product people get more use out of.
