"Don't fall for the hype. A lot of ideas, groups and methodologies are basically cults trying to advertise their consulting services. While I have no problem with that, just remember that when you run into one of these guys and they are quick to shit on the alternatives to their way (and those who built them) to always be very suspicious."

Context:

We had the opportunity to meet 2 very bright people who were heads of their respective communities in a similar area. They were both talking a lot of shit, and getting kinda harsh.

A brilliant dev I worked with, who knew both people for years, took me aside and told me this.

Some cults have cool shit, just don't drink the kool-aid
