To be honest that looks more like a history of really bad projections and extrapolations that failed to even try to account for many other variables let alone the correlations and their causations.
It brings to mind one flaw of the game series Civilization as a game with fixed assumptions - it always assumes food surplus maps to population growth. While it certainly poses a limit past a certain point more food isn't going to help any more than twenty randy husbands will cause a fertile woman to have a full term baby every month.
Food to farm labor's link has been downright economically broken with mechanized farming. People and even land aren't the limit to production for first world farming ability but the limit past which it makes no economic sense to do so.
Hyperbolic growth requiring a singularity to sustain does not imply hyperbolic growth alone is going to give a singularity - unless there are no other limits which will become readily apparent as it is approached.
