The general loss of knowledge is something I've only personally started to notice during the last 2-3 years. For most of my life I didn't even think that we were still at a stage where we could lose valuable knowledge. But it clearly is everywhere, including basic everyday technology such as Electronics, Software, Wood working or even Cooking. My gut feeling is that the knowledge loss that occurs at every generation is non-linear depending on the field, but it is higher than 75% overall, and probably more. The loss rate could be reduced by increasing healthy lifespan.
