"ICE is dead" is an often heard claim, and while it is true in one sense, in the above sense it is alive and kicking: Intelligent design and use of manufacturing improvements to create better products at lower prices, and in shorter timespans.
ICE is al but dead when it concerns internal combustion engines, and the ICE car industry and big oil know it. They just don't want to give up yet, and fight to delay the inevitable, spending about half of their daily profits in the process to protect the other half of their excessive profits on cars and oil.
