It is a worthy cause! Industry & governments spend zillions on material optimizations, I figure if we can chop off some tiny percent of waste, that adds up to zillions of tons of greenhouse gasses and industrial waste, it’s worthy of a challenge.
Also, optimizing computations, how many tons of greenhouse gasses would be saved if FB were 0.05% faster? In fact, how much is wasted with slow computer languages? Yes, that’s right, moving your source to C or assembly might just save the planet
