It would be a comedy sketch if you had a real meetup, but people using their "Hacker News" tone. Lot's of hot takes, fights. Maybe each person has a up and down vote button on their t shirt? Some boring conversation in the corner 2 people listen to. In 10 years time turns out it was the launch of Bitcoin, Figma or Dropbox or something.
That reminds me of a sports talk show I see on the gym TVs sometimes. A few talking heads, and a host who literally gives/takes points from these old men talking football/sports.
