That's the problem we're talking about. It is very feasible but only if performance and energy use is something you want to focus on, while accepting the economic penalty of not prioritizing time-to-market. This is just yet another case of unchecked capitalism and free market destroying the planet. Focusing on energy and resource conservation may be more important as well as feasible, but it's not quite as economically competitive. Unless the industry as a whole decide to do what's morally right, or it is regulated and mandated by the government.
