The reality is people go to conferences (a) to network or (b) to boost their ego. Not to actually listen to talks. Especially in CS-adjacent fields, Github repos with working code are 100x more valuable than conference talks. So yeah, nobody really cares about conference talks or the slides except the loud bearded dude whose moves between rooms questioning the rigor of every talk.
you’re right, people are in a talk because they hope to get access to someone in the room, or for data insight, you either have big visuals or you are a big deal : P
