Human history is a long, messy chain of trial and error. It would be arrogant, hubris, even, to suggest that we know all the solutions to all of tomorrow's problems today. We never did, we never will - the universe is far too complex for that.
So, let not perfection become the enemy of good.
Coal was an improvement, with adverse side effects, on muscle; petrol was an improvement, with adverse side effects, on coal - and so on. If we had not happened on fossil fuels, we wouldn't have been able to sit here indulging in this discussion. Most of us would not have been born because in our ancestry poverty and disease would have been rife to this day without the technologies that actually got us here.
We did not blow it. We did what we could with what we had at the time. That is what humans do. That is what got us here, imperfect as we are.
Assuming that release of stored plant food causes exclusively adverse climate effects and that stopping those emissions immediately, if that were even possible (try to get China and India on board), will invariably cause other crises, and these are not necessarily more benign than what is by some perceived to be a crisis of the climate. Even the highly political IPCC's most pessimistic predictions do not even come close to suggesting Doomsday if we remain at status-quo. IPCC predicts a 3-4% loss of global GDP by the end of the Century due to adverse climate effects assumed to stem from carbon dioxide emission from human activity if we don't do anything other than what we are already doing. But 3-4% relative to what? Can we increase GDP more with less reliable sources of energy? I wouldn't bet on it. Without fossil fuels we would never have been at the high level of GDP we are today, so do we even have a null hypothesis?
There are many things that cause me much greater worry for my offspring than what the climate may have to offer in decades to come. If there is one thing humans have been persistently successful at over the centuries, it is adjusting to whatever climate nature throws at us.
Although we are not separate from nature, humans decide whether a change in nature is 'good' or 'bad', irrespective of the cause. Nature doesn't care. Humans do.
Sorry about the philosophizing - back on track: EV-conversions of old ICE cars? Live and let live. I wouldn't do it - I fail to see the point. I would rather spend my money on restoring the ICE classic that I assume I am emotionally attached to, or sell it off, even for spares, to someone who cares more than I do. If we're worried about ICE classics being totally banned its up to us to prevent it. Supposedly we elect our politicians, and some of them do actually care about our technological heritage. All is not doom and gloom.
