I think this is unfair. These are splinter communities. It's like critiquing Ethereum's community by pointing at Ethereum Classic and Binance Smart Chain.

>Personally, I think PoW may be what brings Bitcoin down in the long-term.

I pretty much agree with this part. I think it'll probably cause very serious issues for it over the next decade. I predict they'll actually eventually move off of PoW or drastically alter the PoW algorithm, but only after many years of infighting and stubborn refusal to consider the possibility.
