It doesn’t work perfectly, but if using smart glasses anywhere outside of the restricted areas of your business risks huge whooping fines, smart glasses will only be allowed in those restricted areas. The same already goes for dangerous tools and hazardous chemicals. On a PC, you can easily screenshot and -record to create documentation or help others. Having this e.g. for a woodworking technique or to show how to replace a specific part in an engine might be a huge value add. But no one needs this shit while grabbing lunch in a public place.

Or at least make them “for professional use only”, and regulate them like they’re body cams. If companies risk GDPR fines, they might self-regulate enough to take care of the problem.
