I am not making a point on whether workers work harder now than they did before. But at the same time, there are clearly ways in which we have had technological advancements that produce goods and services with less input (where 'input' includes natural resources, human labor, etc) than would have been required before these advancements. I used this example in another reply, but (just off the top of my head) computers + internet have allowed abundant knowledge lookup and communication for far less input cost than the services would have required previously.

Generalizing here, there is 'growth due to making people work harder' and 'growth due to inventing stuff that lets us do new things' and whatever your views are on each of these, I think most anti-growth articles ignore the latter.
