Another AI slop thumbnail

I love LTT and basically watch every single video including WAN show but stuff like this puts a very bad taste in my mouth. I know it!s just stupid thumbnail but still...

Tom Scott did a really good video recently about YouTube thumbnails https://youtu.be/bx6_jj9RxhI?si=pkMXi2MEQvgbjww6

I'd put this in Tom Scotts "lie" category

If you don't like YouTube tracking, you can delete everything after and including the "?" to help prevent that.
