I thought the same thing about battery tools when they first started to show up. Never replace corded tools, not enough power, to short battery life. Now look what happened. Everybody uses them, contractors have them, they are powerful and charge faster.
The problem with waste, what to do with them has to be addressed, but im sure that will be taken care of someday
Dont get me wrong im not in favour of EV, I dont see the advantage and have zero desire to own one but I still think someday there will be more of them on then road then internal combustion engines
