Next you're going to tell me that car salesman recommend just leasing new cars, doctors recommend just following the standard of care, construction workers just recommend subbing it out, and your tech friends say just use AWS.
On that note though, most car salesman are somewhat stupid, although the best ones are atleast normal. (I was a cal mechE grad and top 0.2% nationwide car salesman). They also slowly brainwash themselves into believing most of what they say.
