Referencing historical charts is folly.
The charts represent disruptive leaps from CPU to GPU to FPGA to ASIC technologies. ASIC is the pinnacle. Charts from the ASIC period onward will be relevant, but right now the charts show horse and buggy, Model T's, '57 Chevy, and 2013 supercars.
Wake me when it shows just supercars.
The chart is less than two months worth, it's almost all ASIC, the entire CPU,GPU,FPGA net hash was like 50TH/s. or less at it's peak.
