Oh boy, I always had this knack for seeing/testing multiple langauges and when I had first discovered nim, I used to watch some nim youtube related content and I remember someone in nim community pointed out about this same video from the creator of elm that you also mention.

So, I think that I had watched the video and honestly, I will watch it now once again since I don't remember it clearly but If I remember, I really liked it.

A quick search points me to the video, though I am not sure https://www.youtube.com/watch?v=XZ3w_jec1v8
