it's unfair to equate pastoralism with a lack of technological 'advancement'. as far as i know, there's little evidence to suggest that agriculture lead to the nice bits of technology we take for granted. certainly, not having agriculture would vastly change the kinds of technology people develop, but whether it would be less effective is an entirely different question. it seems like a lot of people's ideas about this question are coloured by their views of commercial products as positive and life-enhancing. products as The Exciting New Thing only really arose about halfway through last century as a strategy for coping with excess production. some people think they were a terrible invention, whereas others argue that utility is utility whether or not the initial want comes from the TV.
i mean personally i'm very attached to farms and the idea of farms. my mother grew up on a farm, i spent a lot of time on my grandparents' one as a kid, and i like the imagery associated with them. it would be irrational to assume that farms are therefore happiness production centres for #1 humanity advancement. the more i think about it, the more i feel like my ideas about farms are are constructed based on nostalgia and picture books about how the cow goes moo and not much else. it's "duh mum, meat comes from the supermarket" all over again.
I say agriculture because agriculture is the moment humanity left its nomadic roots behind it - it's also the moment we started managing and controlling crops, and maintaining pools of water and what not to maintain the crops. The large numbers of people that began to live together, all situated in one place which was something that hadn't happened before, we began to develop new diseases from things like mosquitos living in the small ponds that would emerge in our crop fields, get in the crops, etc. etc.
Basically, settling down and tending to crops meant that others could attend to things they hadn't concerned themselves with before due to lack of time, AND they the crops needed protection. If we're all staying in one place, there's things to be done. Houses to be built (builders), storage to keep those crops and other collected items (potters), protection for those crops (first versions of armies). What this led to is something that ALSO never really existed much beforehand, caste systems.
The argument is that if we had never settled down, we may have remained in small, nomadic tribes of people that, while in their own right "savage" in ways (not any different than modern ways really, they killed to protect their tribes just as we do, etc.), did have a certain respect that was essential for a small group of people living together, understanding that to survive they all needed each other and had to work together.
There is tons of evidence to support claims like that, and dozens of books written on the subject (A great one of which is Guns, Germs and Steel by Jared Diamond which is where I lifted the core functions of this idea in the first place, and where he goes into the concept that settling down created diseases which we never faced when travelling in small tribes and have slowly been chipping away at us for thousands of years now in LARGE numbers). I'm not going into it EXACTLY perfect, but I figured this sort of outlook is important to consider when you're discussing matters such as this.
Again, not really my opinion. I'm a 20th century product just like the rest of us, I grew up with and love technology - and I weep for a cage, just like you.
