Lithium batteries were discovered 30+ years ago, and while there hasn't been a major breakthrough in the tech (a single-improvement that 2x+ it) if you look at e.g. prices they have been exponentially decreasing for the last 10 years, and now they are around 90% cheaper than 10 years ago. Make them another 50%-80% cheaper and e.g. ICE simply won't make sense. On Biology for example, isn't Covid19 vaccine and mRNA in general a huge breakthrought?
