Sorry to be holy-wary, but that was outrageous: just watched random pieces of that video until found one where he actually codes, basically vim Python editing.<p>So I opened somewhere around this moment: <a href="https://youtu.be/7Hlb8YX2-W8?t=17039" rel="nofollow">https://youtu.be/7Hlb8YX2-W8?t=17039</a><p>And, first, he copy-pastes some code, and then spends about a minute figuring if he got tabs converted to spaces, including googling a vim command.<p>Then he proceeds to make a loop over some collection next to the loop over an adjacent collection. And he makes that stupid mistake of renaming a variable of the loop, but no renaming in the body.<p>Man, if that's how professional vim users work, this piece of video will be the only proof I will ever need to prevent zealots from even wasting IDE users time to try vim.
