I not only use my EV because I'm a "green" guy, although I have a solar system at home which I love. Aside from the carbon footprint weather it is comparable to gas cars or not (and I don't have the scientific knowledge to weigh in specific to that), the advantages of driving an EV are far enough to be the choice for me.
I'm pretty sure technology will keep evolving and we will have to adapt one way or another unless one wants to stand behind. Remember how computers used HDD for storage with lots of moving pieces and such but now they have SDD with no moving parts and almost paper slim, for me the same applies to almost anything in life when in comes to technology, weather one likes it or not. If one wants to ride a horse across the country it is your prerogative since that person may be afraid or against airplanes, it is all about choices. Not comparing apples to apples but life is evolving, I do not write checks any longer (only online payments) for about 3 years, but some folks still like the old fashion way and that is ok too, their choice.
I'm sure, and hope, that EVs won't merely rely on batteries produced with lithium in the future, perhaps there will be a "mechanism" (not a battery per sa), who knows. But again for me the benefits of driving an EV are far heavier and as I mentioned before, once you drive an EV you ain't looking back.
I drove gas cars for 40 years until I drove my EV, so I can compare one versus another in terms of benefits as a consumer.
