Even if the 0.1% figure is correct, I find it a lot of energy (and growing) for something found useful by so few. Reducing it to a percentage and saying it's ok

Even if the 0.1% figure is correct, I find it a lot of energy (and growing) for something found useful by so few. Reducing it to a percentage and saying it's ok because it's within a rounding error is like taking the entire population of New York City (8.38 million), killing them all, and saying it doesn't matter because it's "literally a rounding error of global population (0.1%)".
