out of all of the semi/actually-obscure issues that people on HN talk about, meta glasses are not really all that obscure.

my local gym has posters up forbidding them. my non-tech daughter has asked me about them. the college i teach at has policies about them.

their banned in courts in various countries. they've been criticized in mainstream outlets like the guardian, BBC, CNN, business insider, national post, yahoo, and the independent. (i dont think any of those outlets are reasonably considered "tech pubs read by a statistically insignificant number of people")
