It depends on what we define as progress. At times nuclear power was considered progress while it's no longer now (at least to that extent). Why couldn't we consider a society with less technology as progressive? Learning that less reliance on technology makes us more resilient as individuals and as a society. Obviously there are areas where we didn't want to downscale such as medical care. But there's a lot of technological progress that does not contribute much value to society in general but to concentrate wealth in the hand of a few people.

EDIT: also so-called "breaking your back" has the same effect as going to the gym. Sure I am aware that there are really back-breaking jobs and they should be helped by machines. But there's no rule to say that the helping machines need to to all of the work. A moderate amount of physical work is just beneficial to everyone.
