Don't forget the bot trained people, who are afraid to think for themselves! About a decade ago one of my hobby groups was sad about a product that was taken off the market. I did some reading and realized that the product was essentially oxyclean without detergent. When I suggested we try the appropriate alternatives the thread went off on me. Downvoted to oblivion Posted my findings on another forum, they considered the idea, tried it and now considers the substitute standard practice. Eventually this inability to think and experiment will cap the progress of hobby sub's and send experts to other places.
