This is like saying that pollution is a recognized issue with fossil fuels and while it offers challenges they are understood and engineers are keen to address this.
There aren't always easy solutions and you can't hand wave aside a massive problem because 'our best people are on it'
If fossil fuels producers had had the same level of awareness of environmental issues when that industry began we might not have the issues we have now, I think it's a poor comparison, my comment was acknowledging the issue and positing that an iteration of the technology could mitigate the problem.
Costs (of EVs) are passed onto the consumer and thus self-regulate, whereas many of the costs of crypto's wasteful energy usage are distributed among society.
