Famous and highly cited energy theorist Vaclav Smil was still calling them an overhyped dead end 5 years ago, a decade ago he said "The myth that the future belongs to electric cars is one of the original misconceptions of the modern energy era".

And he literally wrote a book published in 2015 on the topic of energy density.

So I'm glad it's obvious now with 20/20 hindsight, but it seems a lot of people can be wrong about this stuff and have their opinions promoted.
