Everytime somebody says useful features will be merged with Bitcoin... we've been trying to implement a scaling fix for almost four years. Now an Altcoin that is pretty much just a few magic numbers away from Bitcoin (meaning it is easy to swap in every well written Bitcoin app) implemented the fix in under 6 months.

Sidechains are the only solution to that, and at this rate Trump's second term will be done before we get anything changed in Bitcoins codebase.

People have the audacity to suggest a POW change, why would any miner pour capital into Bitcoin when even if they agree with consensus, their entire investment could be thrown away overnight. A POW change would kill Bitcoins only actual advantage (hashrate).
