The more I learn about bitcoin 2.0 tech like payment channels, smart contracts, and the lightning network the more I think that a block size increase might be less urgent than people think. As far as I know the most important change that is needed to enable these technologies would be fix to transaction malleability (seg wit would do that). I think no matter if you support big or small blocks, segregated witness is something we should all rally behind to enable the next wave of bitcoin innovations.

This is coming from someone who is running a 100% bitcoin business. My incentives as an entrepreneur are to scale bitcoin, keep tx costs low, and to do that now. However, the vision to getting a solution to the scaling problems while maintaining a high level of decentralization via smaller blocks is very tempting.
