Your missing the point (ill give you the benefit of the doubt that its in good faith) battery tech advances very slowly but most of the "ambitious" claims for electric cars seem to think that some magic discovery will result in a step change.

I am using its as analogy that anyone familiar with basic technology would understand.

Battery technology is increasing at a steady rate of 8% per year. Everytime you hear of a breakthrough it's at least 10 years away from being production ready.

Just to add 8% a year is doubling every decade. If you hear about something 2x as good that takes 10 years to become mainstream, then that's progress as normal.
