Yep, I've seen these videos before and am aghast at how nonchalantly they work with nasty stuff.
Me - I use PPE when working with pretty much any solvent or etchant. And that includes gloves and goggles at a minimum. And if the stuff is not nice, I'm using a stick of sorts to apply (wood, metal, glass; whichever's less reactive).
And if I were dealing with things like HF, you can bet your ass that I'm building some sort of automated setup. HF spattering on a webcam lens means a loss of $50. HF spattering on me means I possibly will die or suffer horrendously. Same with lasers as well. Telepresence is so much safer, and failure means a few hundred dollars of equipment replacement.

This stuff is the active ingredient in glass "etching cream". Amazingly, many DIY craft videos on YouTube demonstrate it WITHOUT USING GLOVES!

Armour Etch doesn't have HF, but it does have other fluorides https://www.msdsdigital.com/armour-etch-glass-etchant-msds
That's interesting. Thanks very much for the correction, and the link!
