It just give you an idea of what it would take if the Diff doesn't change for a year. We all know it doesn't work like that. Why is this so outrageous ?
Because Kano likes to be a pseudo-intellectual.
In his mind:
Chance of you finding a block in one day: 1 in 1,929.6
is, somehow, magically different than
Your Average Time per Block: 1929days 14hr 58min 29sec[1]
He just can't grasp that saying "1 in 1,929.6" and "average of ~5.3 years" (based on 5.5TH/s) are
the exact same thing.
Basically if you're not a sycophant, you're wrong even if you agree.
[1] 1929days 14hr 58min 29sec = ~5.3 years
