Am i missing the joke? ChatGPT tells me 3% of 100 is 3, not 0.18.
.18 is 3% of 6. This might mean something, but I don't know what.
Off topic: what are you trying to signal by saying chatgpt helped you with arithmetic here?
Is it supposed to give more weight to what you are saying?
I think the joke is people trying to figure out why 0.18. I, personally, enjoy it.
When I first read it I thought wait, 3% of 6 is 0.18, but then I realized no I'm a dork because 6 is the age of the kid, whereas the number 100 is written as a word hundred, hence I decided to write "HN poster responds:" with quotes around my first non-coffee aided thought because I thought it was funny. I guess I should have just made that full statement, but I do have a tendency to rather oblique communication strategies.
on edit: basically because I thought hah, this is the kind of mistake I always see poor tired folks make on HN and making the dumb comment and here I am making it!! This is a classic moment!
