Does the modern cryptocurrency community need this principle of Satoshi Nakamoto?
It depends on the principle itself
I kinda feel the same, this world is turning to a centralized world and only people with big money will rule everything. But it isn't end yet, Satoshi has given the idea of decentralization and invented Bitcoin as a little proof of his idea.
Now, it is our job to think how to improve and make the his idea as a complete real product.
Ok
What do you say if I tell you that I came up with and developed such a POW algorithm that solves all these problems?
https://bitcointalk.org/index.php?topic=5207996.0While your algorithm could resist ASIC/GPU/FPGA/CLOUD/MAINFRAME, but it doesn't solve all problem.
1. Rich people still could buy lots of CPU and build mining farm
2. You're replacing possibility of monopoly from ASIC/GPU manufacture to CPU manufacture (Intel, AMD and ARM)
3. You haven't solve hashrate domination by mining pool and mining farm
