We need the engineers to tell ideologues like myself what is possible. Great engineers like Gavin Andresen and Jeff Garzick are saying that an increase to two megabytes is possible, I have no reason to think that is not the case.
Great engineers like Gavin and Jeff? Is this some joke or an insult to the actual great engineers of the modern world?
2 MB is possible obviously, but it is redundant in comparison to SegWit. As things stand now, the deployment time for either option is going to be similar (even if Classic takes off). 2 MB blocks do not bring anything with them, SegWit brings a lot of benefits (and the increase in capacity is just a bonus).
This bolded bit is an odd thing to say. Some really bright folks think we can have both.
