Most of them just talk bullshit at business conferences.
I've been to a couple, it is literally just people trying to compete to find the best way to disguise they want to sell you something. So much so we would time to see how long it took for the "catch" to come out.
Them "Oh, so you are in IT"
"Yes, we do X, Y and Z"
"thats great, what sort of stuff is that" (you can tell they dont give a shit)
"it's mostly x,y and z, but a more detailed explanation"
"Do you need a cheap supplier of bathroom supplies, toilet roll, handwash etc?"
"No, we don't use much we only have 1 toilet"
"Ok have a good day"
