Oh, Myers-Briggs Type Indicator, you unkillable scamp.
This video, from Vox, gives a concise historical perspective on the scale, describes how popular it still is, and summarizes several of the arguments against the scale.
This video explains why the ol' MBTI is not particularly useful. Good for debunking psychology myths and good for explaining reliability (in particular, test-retest reliability) and validity.
I like this link in particular because it presents its argument via both video as well as a smartly formatted website. The text in the website includes links to actual peer-reviewed research articles that refute the MBTI.
