Not necessarily. The industrial revolution suddenly created exponential growth because of the discovery of large seams of coal. Wood doesn't burn hot enough - and there arn't enough trees - to run powerful steam engines so without coal , and then oil, we may have carried on developing slowly and eventually created a technical society - though not using fossil fuels - but it would have taken a LOT longer. However in the scheme of the lifetime of a species an extra thousand years here or there is nothing.
