I don't think so. I think he just wants to grow Bitcoin ASAP. You have to understand that we are at war...
I believe we might have to move to hybrid PoW/PoS down the line (next 5-10 years). We need TPS speed from PoS but we might need to keep Miners to ensure proper circulation of coins.
GPU Miners are like Gaming Rigs with many cards. They generate around ~400 MH each depending on strength. Only takes a few AntMiners to disrupt a majority non-ASIC. Network TH>GH>MH>KH
PoW requires very strong miners to be powerful enough to process a block. A single outdated miner is too weak to break even in rewards. Thus a pool of Antminers are required for profit
Validator coins scale very fast (1500 TPS). Not all BCH users will full node (DL whole chain), thus SPV which still works with PoS or PoW/PoS Hybrid. Unless ASICs become far stronger.
