Because you'd need to trash the old GPUs in order to make room for new GPUs. Right now new GPUs get online mostly in new DCs. TSMC fab capacity is much more limiting than DC building and it will likely keep being the case. It's much easier to build a DC than a fab.
Europe has passenger trains that work. What would be a short flight in the US, e.g. London to Paris is done more my train through the chunnel than flying unless you got a connecting flight.
Step 2, put the needle on a gantry (I suspect you'd need more like 5D CNC to enter the pore with the right angle) and seek and destroy hairs... As it is it saves money but not time nor skill...
That's one of the reasons I can walk in the main office of my registrar within an hour. It's clearly not available to everyone but it's especially important that if you can't do that you can at least conveniently sue your registrar... So at the very least in your jurisdiction.
The miners are the middlemen, and they can chose to take your transaction or not. Should bitcoin ever be actually used for payment, it's not to too far fetched to think miners could be forbidden to validate transactions involving a blacklist of addresses...
Partly true, the miners decide. However, "the miners" is not a single person or group, but are distributed world wide under control of different people and pools having different incentives - albeit, making money is the far most common incentive. I.e. a miner can reject your transaction, but you can gradually increase the fee (replace-by-fee) until someone picks it up.
Plus, on-chain transactions would NOT be used to pay 10€/Month subscriptions. The lightning network (a bitcoin layer-2 network) handles transactions instantly and with lower fees. No miners involved in individual payments here (only for channel creation).
The general point is not. Iceland and Easter Island were fully deforested way before the industrial age. Countless species went extinct in Britain and more examples abound.
Britain was a little bit industrialised even before the steam engine. There were windmills and water mills. Steam massively accelerated it, but industry did exist before.
Commons in England were being enclosed in the Tudor age. It caused a great deal of social unrest, even rebellion. It had little to do with technology, and was mostly caused by population growth.
