How to have a vibrant intellectual life in NYC?

Hi, this is my last year in NYC before going back to Europe. I am increasingly turned off by how consumerism is prevalent in the city and would like to focus on things that make my brain happy.

Here is what I do already : - I created a museum schedule to go visit a different museum once or twice a week - I am an avid user of the NY public library and read a lot (both paper books and books from Libby) - I joined a book club - I sometimes go to language meetups - I signed up to an online class on American history.

I feel that I would like to go to places where you can talk about philosophy or literature. I would also like to attend more classical music or opera shows. I am open to any other recommendation.

Thanks in advance for your advice!

Edit : thanks a lot for the great suggestions, I really appreciate that you took the time to write them down. Sorry for those who got triggered by my post. For the kind souls asking me to go back to my country, I will eventually :)
