I think there are four key places where we've truly innovated over the last decade or so: 1) Solar power is vastly improved today and on a trend that follows Moore's Law 2) Cell phones can be found all over the globe (all thanks to innovations in tech) 3) Rechargeable batteries are lasting longer and making it easier to take complex machines into difficult areas 4) The ability to talk, tap, and rotate our phones/screens is a big innovation It's pretty impressive to me. Some of these are incremental pieces that are built on top of decades of research. However that does not diminish the true innovation that led to Lithium-Ion batteries being so dominant today vs. 10 years ago.
