On: Flaws in Bitcoin make a lasting revival unlikely

[wavepruner]

After the initial ASIC "gold rush" Bitcoin mining is trending towards decentralization again. ASICs do not mean an eternal approach to centralization, it is just a temporary step along the adoption curve. See https://www.blockchain.com/pools

Also, ASICs are the most energy efficient way to perform proof-of-work.

Proof of work is oblivious to efficiency. Efficiency gains are met by equivalent increases in mining difficulty, since the network attempts to calibrate towards a constant mining rate.

Equivalent increases in mining difficulty is the goal, as that secures the blockchain.

No it doesn't if not everyone has access to the ASICs. If 30% of miners use highly efficient ASICs that are twice as fast they become the majority.
