I don't think it's that simple. Human beings evolved while spreading culture, for far, far longer than we have been writing, longer than we have been homo sapiens even. It is a core part of what we are, so understanding it and accepting it and examining it without bias is important. I'm not entirely convinced that we can preserve information for generations. We can't even preserve web sites for 2 decades, link rot online is a real problem. That's modern technology with solid state drives and worldwide communication. Language evolution makes this problem even worse. We can't even agree on what the founding fathers of the US meant with some parts of the constitution (granted, there are and have been deliberate efforts on that front but there are legitimate questions stil) and that's with the same government still operating under it while it's people still speak the same language! I don't think information propagation across generations is a solved problem now that we have writing and solid state drives, and beyond that tradition is not going away because it's as much a part of who we are as language and fire.
