I came across a video about older vrs newer mmo's that I think has enough parallels to the "what is old school" topic & it lines up well with a lot of the various subthreads of specifics that oldschool was/wasn't.
The video & paradox it talks about also sheds some light on why some people say 3.x was or could be played with an old school style & why 5e discussions so often zero in on how 5e is risk free or how the system itself fights any efforts to add risk to it. People don't want to add those elements of risk back to their game because they want to run a DCC funnel meatgrinder& cackle over the death of PC after PC, they want to add it in order to bring back the positive elements that came with the risk.
