At that time (2011), we had just hit 10 Petaflops. Today, a US company announced they are developing a 300 Petaflop machine (150 Petaflop sustained)
The original estimate I read was that a human consciousness emulation would take about 10 Petaflops, but that got bumped a few years ago to 100 Petaflops.
Get ready for the future, digital consciousness is now a real possibility. OK, there is a little matter of Software, but I'm sure there are a few smart guys out there working on it!
