Well yeah, I think I remember that happening actually, and at the time they were correct: a lot of work had to go into lithium batteries to get them to the commercially viable state that they're at today. I'm glad that work was done, and that people were excited about it, but I am slightly concerned about the broader trend of the public/journalists not being able to simultaneously a) be excited and b) understand that even a big breakthrough is more than nothing but less than everything.

Also I'm actually gonna be working on that exact technology and I'm extremely excited about it!!
