Quick math: In terms of total expected suffering averted, inviting a group of friends to a barbecue where the main meat is beef is probably more impactful than eating a vegan meal by yourself.
According to Faunalytics' Animal Product Impact Scales, a serving of chicken requires approximately 10 times as many days of animal life to produce as a serving of beef (not adjusted for quality of life or moral weights). Additionally, most seafood is much, much worse than this. If this meal prevents your friends from going and eating those other foods, tricking them into eating beef will likely do more good than eating a vegan meal by yourself.
Still, this may not be as impactful as saving your money and donating it directly to impactful charities. Saving a single dollar on food and donating it to the SWP will probably do more to reduce suffering than hosting a barbecue.
Also, you might expose yourself to various forms of value drift by hosting a barbecue, but I could see this happening in a net positive (hosting more barbecues in the future) or a net negative (giving up on veganism entirely/permanently failing to convince any of your friends to give up meat) direction.
Aimed at an audience newer to EA/AI safety
It seems like many people have been confused lately about why 1) AI safety orgs are in desperate need of good hires and 2) org hiring rates are very low. My understanding is that there are many reasons for this, but a 2021 post states it pretty well:
The best career advice seems to be to focus on developing a rare and valuable skill that orgs currently need. In AI safety, this skill is a combination of specific context, agency, mission-alignment, and strategic vision. You can develop it by reading a lot, writing out your thoughts, talking to people at events, and completing real projects.
It's hard to do really impactful work. You need a plausible explanation for why your efforts are the best way your salary can be spent. This takes time, effort, and careful strategizing. Most of the world has high schools, colleges, and internships to train people for jobs, but a similar system is only recently becoming legible for AI safety and EA. The rare skills are rare for a reason. Still, I think the broader EA community could do a better job of communicating what it means for these "talent-gaps" to exist.
I'd agree that the EA/AIS community could do a better job of communicating what it means by "talent gaps." Further, I think the feedback loops on failed attempts to secure a role are beyond poor (mostly just pointing to upskilling programs/research fellowships). While I get that orgs already have limited bandwidth for admissions, I think the feedback loop pipeline is a piece of this puzzle that should be improved.
