I did, and enjoyed it as a good pop-sci outreach video, and do not fault it given that's what it is. The lim v->c analysis is standard and well-presented, but his conclusion about photons' time is liable to confuse people (including other physicists who aren't relativists). I refer you to my comment elsewhere in this thread <https://news.ycombinator.com/item?id=36537015> which has a paragraph about this video (your link having partially motivated my comment), and which explains that it is common for relativists to use affine time for massless particles.
Yep, after years of being a couch- and desk-potato, this got me out and running.
That, and having a young and energetic dog in the early stages of lock-down!
I've managed to stick to 5-10km every other day (though it's a challenge in the winter, admittedly), and did my first half marathon in 2:09 a couple of months ago.
