Thought I'd pop this video on Patreon as well in case any of you don't follow my second channel (understandable) and don't follow YouTube drama (even more understandable).

In the most recent Veritasium video Derek points out a wrong thing I said at the end of my prisoner puzzle from 2019. And he's right! So I whipped-up a quick response video last Saturday.

Which brings me to two things to thank you all for. I feel like part of the responsibility of having your patreon support is the onus to respond quickly to new events. Sometimes that means interviewing a Google engineer who likes to calculate pi, and sometimes it means using a Saturday to film a silly reverse-Derek video.

Secondly, thanks for the error checking you all help me do! Both before a video is public when I ask nicely and after a video is out, every time whether I like it or not. Helping me add corrections to the video description takes some of the sting out of these gotcha videos.

Nice vid Matt :) It was fun. I actually used this riddle for my brother (math scientist on doctorate now) - on his 30th birthday 4 days ago. I would send you an image of it, but it’s not possible on Patreon :/ Correct answer after he solved it was “it approaches limit 30ish” - and that is how old u roughly are. He is big fan of limits and infinite series. And he liked a lot your random silly treats i received - like the christmas lites with my name - or equation for triangle, … So he will watch your vid too - since it’s connected to his 30th birthday now :) Good memories - thank you both.

I had great fun helping out with the original video. Love your response.

Best vid yet mate. ***spoiler. The shamelessness and then the smugness 🥰

Matt, doesn't being reverse-Dereked mean, you have been Dekered?

It doesn’t sound good. It would not catch on. ReDereked - sounds better than that.

I know it's hard -- but I suggest you feel flattered that someone thought a video you posted two or three years ago is important enough to comment on. Don't let this kind of thing upset you or get you down. I am very happy to subscribe to your videos. And yes, the guy could have been less snippy and more polite, but that is life.

I want to know where he got the whiteboard that you could flip it over and it would have prewritten results then you could flip it over and it would have more prewritten results.
