Yes, I had also read that one as well! It has been an interesting time, Ethereum #defi also revealed some broken assumptions... It appears that as crypto gets more use, that some of the original assumptions are being seriously tested and in some cases broken. It is good in a way, these things need to be resolved...

However, I wonder if the original witnesses have much vision beyond reclaiming their spots... A hybrid would also be interesting, but low cap coins like Steem are vulnerable in a pure POW... I wonder if the hybrid is protection enough?
