Underrated is relative. My position is something like "most people should consider going to >1 EAG talk" and not "most people should spend most of their EAG in talks." This probably most applies to people who are kind of like me. (Been involved for a while, already have a strong network, don't need to do 1-1s for their job.)
There's a meme that 1-1s are clearly the most valuable part of EAG(x) and that you should not really go to talks. (See e.g. this, this, this, they don't say exactly this but I think push in the direction of the meme.)
I think EAG talks can be really interesting and are underrated. It's true that most of them are recorded and you could watch them later but I'm guessing most people don't actually do that. It also takes a while for them to be uploaded.
I still think 1-1s are pretty great, especially if you're
- new and don't know many people yet (or otherwise mostly want to increase the number of people you know),
- have a very specific thing you're trying to get out of EAG and talking to lots of people seems to be the right thing to achieve it.
I'm mostly writing this post because I think the meme is really strong in some parts of the EA community. I can imagine that some people in the EA community would feel bad for attending talks because it doesn't feel "optimal." If you feel like you need permission, I want to give you permission to go to talks without feeling bad. Another motivation is that I recently attended my first set of EAG talks in years (I was doing lots of 1-1s for my job before) and was really surprised by how great they were. (That said, it was a bit hit or miss.) I previously accidentally assumed that talks and other prepared sessions would give me ~nothing.
edit: Someone mentioned in person that they think EAG talks just got much better recently, so I just started going to them at a lucky time. So, if you've gone in the past and were disappointed, now is maybe a good time to try again.
Chi - good points.
Having attended over 100 science conference in my 30+ years of academia, I've realized that attending live talks has some hidden advantages over just 'catching up later with the videos', or 'just doing 1-to-1 conversations'.
First, if a high enough proportion of people at a conference attend any given talk, they all have something to react to with friends, to discuss at social gatherings,, and to serve as an ice-breaker when meeting strangers (e.g. 'Hey, what did you think of that talk by X about Y?'). This works best for plenary talks where there's only one talk happening at a time, so everybody's coordinated on that topic as something important to consider.
Second, live talks induce a level of collective emotional engagement, a kind of mass hypnosis, or a tribal ritualistic mind-set, that heightens the affective impact of the talk. This might be as 'efficient' at a strictly cognitive level as watching the talk later at 1.75x speed. But it can help the ideas sink deeper into one's heart and brain, as it were.
Third, attending talks incentivizes speakers to do a good job of prepping their talk, clarifying their ideas, simplifying their data, and polishing their narrative. If nobody shows up, it's disheartening. If lots of people show up, it's very encouraging -- and it sets up expectations that one must do one's best in future talks at the same conference. Obviously there's a game-theoretic problem here that people can do 'social loafing' or 'free-riding' on the talk attendance of others, without paying the costs oneself. But this can be offset if a research community has strong social norms that, if you attend a conference, you really should be attending lots of live talks. People can notice who's in the audience, pulling their weight, encouraging the speakers to excel.
Fourth, great live talks can be memorable events that can reinforce one's intellectual and ethical identity, and make one feel connected to an ongoing tradition of ideas, and to the 'life of the mind' in general. Decades later, I can remember seeing live conference talks by inspiring thinkers like Peter Singer, Richard Dawkins, Daniel Dennett, Steven Pinker, Leda Cosmides, William D. Hamilton, Margo Wilson, Geoffrey Hinton, etc. They're among the highlights of my intellectual life. And they're motivating in a way that reading their books isn't. Conversely, there have been plenty of talks by major thinkers and up-and-coming researchers that I failed to attend, and that I'll regret not seeing.
So, in a very narrow, cognitivist sense, it might seem more 'efficient' to watch conference talks later, as if they're no different than any other youtube video or podcast. But that misses out on at least four - and probably many more -- hidden benefits of actually being there in person -- socially engaged, part of the tribe, incentivizing the speaker, and setting up precious memories that can keep inspiring one for decades afterwards.
