Sometimes the high impact game feels weird, get over it.
I have been in lots of conversations recently where people expressed their discomfort in the longtermist communities spending (particularly at events).
I think that my general take here is "yeah I can see why you think this but get over it". Playing on the high impact game board when you have $40B in your bank account and only a few years to use it involves acting like you are not limited financially. If top AI safety researchers want sports cars because it will help them relax and therefore be more 0.01% mroe productive (and I trust their judgment and value alignment) they are welcome to my money. Giving them my money is winning and as far as I am concerned it's a far better use of money than basically anything else I could do. To be clear, I know that there are optics issues, community health issues etc. but sometimes we can spend money without worrying about these things (e.g. retreats for people already familiar with LT).
Yes this would feel weird, but am I really going to let my own feelings of weirdness stop me helping billions of people in expectation. That feels much more weird.
I agree with the sentiment, but I wouldn't put it quite as drastically. (If someone actually talked about things that make them 0.01% more productive, that suggests they have lost the plot.) Also, "(and I trust their judgment and value alignment)" does a lot of work. I assume you wouldn't say this about any researcher who self-describes as working on longtermism. If some grantmakers have poor judgment, they may give away large sums of money to other grantmakers for regranting who may have even worse judgment or could be corrupt, then you get a pretty bad ecosystem where it's easy for the wrong people to attain more influence within EA.
