I don't think we will ever lose all this knowledge altogether. Just that certain parts of the world might be rough for awhile. But I am planning on heading to the easier areas if mine goes belly up due to Nukes. The only thing that worried me about Y2K was accidents, because the people with the skills would still be here to fix it even if Y2K had brought down certain systems. The good thing about picking up as much knowledge & tools as possible that are constantly discussed here is you could ride out a lost in the woods or another Katrina situation with very little pain. Folks at this site would have been on the highway before the levies broke and if that was impossible they would have plenty of water jugs filled up, etc.
