Yeah but I didn't have to learn how Spear.JS worked in the new monthly update in order to go catch food. The skills I needed and my relationships did not change as often.
Food is actually a profoundly bad example to make your point, because food security before modern times was non-existent pretty much everywhere, even if you had the necessary skills to grow or catch it. :)
The supply of food was unstable but the means to find it was not changing all the time. Once you built up a certain foraging / hunting skill the skillset is done. You don't have to relearn it 10 times.
