 Combustion engine is 130 years old. The auto engine, I think, is 1896. We've been developing that tech for 130 years. The first time you saw an electric vehicle really on the road with any scale ambition was 2008. So we're in the infancy of the tech. So what we will see over the next 5, 10, 20, 25 years out of electric vehicle technology will be mind-blowing for all of us.
