The main problem side chains has introduced for me, is they can steal my technology and put it in a side chain. So I will just have to put it in a side chain first and make sure I am siphoning value from BTC in a way that can't technologically be improved upon. I know how to do this because it was already necessary in my design.
So everything is falling right into place for me. Monero has eventually been co-opted by side chains (unfortunately).
The above is incorrect. On further thought, I have solved the economic threat of Blockstream's
pegged side chains (it threatened to turn all innovation into Communism!). There is a win-win solution for side chains and altcoins to co-exist.

Exciting times ahead...
side chains will send more BTC wealth fleeing into altcoin investments. It is counter-intuitive, but Adam and Gregory are achieving the antithesis of their stated effect.
