... a group of people had to start from scratch on a new planet. They arrive with knowledge, computer readers that last a few decades. And they have a few tools, things they brought in packs but they couldn't salvage much from their ship. It's now two generations later, they've established a well hidden village, good food sources, they are thriving hunter-gatherers. There is a technologically advanced population elsewhere on the planet that poses a threat they have to stay hidden from. So I present this as people that have little technology, not much medicine and a couple people in my critique group keep saying they don't think it's credible these people wouldn't have more technology than in my story. So if you had the knowledge of a technological society but none of the technology and started from scratch, plus you had to learn about the resources in your environment, how advanced would this population be in 2-3 generations? This is a request for opinions, so it's not something I can research and there is no right and wrong. Thanks in advance.
