What the debate around bitcoin is currently focused on is not what is sustainable or how urgent the need to increase the blocksize is. The debate is around what the precise use case of bitcoin is - an ideological crisis, not an engineering crisis. A vision crisis, not a management crisis.
The companies and individuals who approach bitcoin technology with a 20th century mindset will find no success. They will seek to harness the innovation of Satoshi's invention, and in doing, will slowly realize that the killer application of this technology is to render them obsolete. Bitcoin is an evolution in our concept of the corporation, and a blueprint for decentralized, trustless, openly accessible commerce in the 21st century.
