I love using replit to write tools for completing small tasks. I recently used it to send out a SMS via twilio to my entire hs class for our 10 year reunion.
The "amount of human lives cost" is also not a real thing, because we have an incomplete picture of elasticity for market substitutes for energy demand (which is nearly all goods, because they all require energy)
Point is - using your dryer does not actually cause human suffering. This is a simply a utilitarian argument with an incomplete picture, the structure of which is often utilized to promote atrocities like communism, genocide, etc.
Unscientific, sensationalist, and pretty much wrong.
It’s just not a great argument, and doesn't consider the opposition argument - the human rights benefits (for people fleeing war zones, in predatory monetary regimes, etc.) are worth the electricity usage – because people/the market are valuing it that way.
Dryers are unnecessary - we could airdry all of our clothes, but we value the convenience it brings. The value that bitcoin brings in terms of human rights is much greater than the convenience of dryers, yet we hear nothing about "banning dryers" or "dryers killing people".
