To some extent it is accurate. Only a finite amount of knowledge can be applied to a task and excess experience doesn’t bring any additional benefit on its own.

I had an extremely religious teacher in secondary school. He had a habit of threatening other staff, tradesmen, drivers in front of his pupils with “I know taekwando”, then relising what he’d just done and repenting/distracting with “let us pray”. One morning we came into the classroom to find him in a huddle with his union rep. Turned out he’d spent the night in jail after being arrested affray (fighting).

For almost all religious people their faith provides guidance and comfort, but you don’t want to encourage the nuts.

I don’t know how valid this is, but I heard county and district councils use government bonds to secure more favourable loan terms. When Liz Truss upset the UK bond market the cost of borrowing rose as the value of their bond assets dropped. The county council where I live is now spending as much on servicing debt as it is on fixing roads. (Roads, although not the most important responsibility of local government, are a visible indicator of their capability.)

I wonder what made youTube decide to fix this loophole? These days the vast majority of people use phone apps or smart TVs to watch. The number of people using Firefox plus ad blockers must be quite small and it’ll be a constant effort to keep updating their anti ad block algorithms.
