Advancing to farming is not the determinant of advancing civilization. That's a capitalist bias. The development of artistic expression and culture, knowledge and science, is why our civilization developed. And the pressures of population expansion. The more humans, the more smart people are around, the faster civilization develops. The availability of resources are the limit to population expansion, not the means of obtaining them.
Civilization advances on the back of its culture - the arts. As culture develops, so to does the level of civilization. Irrespective of the means of production of food, the advancement of art and culture - theater, writing, entertainment, leisure, discovery, knowledge, philosophy, the pursuit of happiness - will push civilization. The limitation on the advance of civilization is the availability of resources, the depths of the educational system, and the advancement of science.
Hunter-gatherers from 8,000 BC, plunked from their cave and dropped into a home in the mid-1800's, would really have no problems adjusting. Everything was done, basically the same way. Food was cooked with fire, water was drawn by hand, and people still traveled by foot or by animal. The tools were just stronger, sharper variations of what they had in the cave, but they did the same job in the same essential way. Some skills re-training and familiarization would be all that was involved. Farming or hunter-gathering made no difference. But only 150 years later? Nothing was done the same. It was science and technology, not any change from hunter-gatherer to farming, that made the difference.
In fact, when cultures do not need to worry about survival, when food and shelter are plentiful, humans spend more of their time and energy on cultural pursuits. Just look at the rich people of today.
However, the civilization will certainly take on a different direction. Look towards ancient Rome for your answer (not primitive societies). When resources are abundant, fighting for territoriality is lessened, and so the developments in civilization will be in the direction of artistic expression instead of weaponry and defense. Jewelry and adornment. Creativity, writing, philosophy, housing, theater, entertainment, dancing, schooling, teaching. Even hunter-gatherers require religious comfort, a sense of belonging, companionship, communication. Human knowledge and intelligence was an evolutionary biological trend. The fact that its evolutionary path lead to farming and cultivation is an artifact. What is oft forgotten is that when the hunter-gatherers returned from their quests, they celebrated in a community, and artistic expression and communication survived even in caves. Humans started farming BECAUSE we were a social, communal animal, NOT the other way around. We would have developed our culture with or without farming. It would just be different.
Farming allowed humans the freedom to pursue artistic expression once our needs were satisfied. One could easily make the claim that we pursued farming in order to allow us the time to pursue artistic expression. If our needs were satisfied WITHOUT the need for farming, we would have gone in the same direction anyway.
