It wouldn't matter if the inflation slowing (what dan considers to be "harm") were disproportionate or not. If it's disproportionate, then the less CPU-intensive currencies (which are also more eco-responsible) would have a well-deserved edge.
If the effect were proportional, then it would be less disruptive, which is a little less than ideal from an environmental standpoint. But in either case the "falling sky" narrative is wacky, and I hope that no one seriously uses it as a basis to rationalize the unethical consumption of Intel products.
