Three years. People have been making issue tickets for three years about Bitcoin's block size.
"Core's" response was always to suggest an indirect fix to this by enabling SegWit.

Incorrect. 140% is the common number floated around.
>doubles the blocksize
140% block 'capacity' while using 400% more bandwidth. That is terribly inefficient.
>enables future efficiency gains
Substantiate your claims.

Substantiate your claims.

Funny how Core halted development of Bitcoin for several years now up until now.
Now there is a frantic dash to get SegWit implemented as a fix to the block size issue even though it does not directly address it. What SegWit DOES directly affect though is the ability for Blockstream(Core) to roll out for-profit products that use Bitcoin as a settlement layer. This is the vision AXA[1] Strategic Investments and others have for Bitcoin and they are using their investments in Blockstream to make it happen.
