by his assumption, hardware should be 10,000x faster now. ASICs may make the processing that much faster, but not everyone has access to that, and we don't have 10,000x storage, memory, memory speed, internet connections, etc.
Yes, Satoshi is wrong, but your calculation is also wrong. In the last 14 years, the speed of processors should have increased 128 times, which has only increased 10 times. Note that ASICs are used to find hash blocks and full nodes must be stored on a personal computer or servers, Satoshi's email was about full nodes. https://m.primal.net/HeoQ.png https://m.primal.net/HeoR.jpg
