I'm not aware of a strong functional benefit of electric versus combustion. But digital cameras had strong benefits over digital, so I don't think it's a good analogy.
In general, I don't think analogies are for making arguments, because people focus on the difference between the analogy and what it's being applied to, like I just did. In education, to teach a new principle, I think they are great.
Accelerate faster than a combustion sports car, no expensive engine maintenance etc. And since the only major cost of electric cars is the battery they will go down in price as we get better batteries and very likely get cheaper than combustion cars pretty soon. Electric engines are super simple, only reason combustion cars are even competitive today is that we have invested so much research into building combustion engines.
