Yes, I would be happy to answer. I would not speak for Ms. Laidlaw; however, we are friends and colleagues.
Specifically on age verification technology as it is currently designed, there are a couple of problems. The first is that almost every age verification method that is currently used requires you to divulge personal details, which means that your Internet activities are being tracked by somebody in some way. There are some computational efforts to reduce that, but it is a first-order problem with the technology.
Another set of approaches uses biometrics—for example, the shape of your face or certain characteristics—to try to determine what your age is, and those approaches suffer from significant inaccuracies. Also, they collect a very sensitive form of information—or at least they process it—which is biometric data.
There is research under way that seeks to implement age verification in a way that causes fewer privacy harms, but as far as I know, we're not there yet on developing that technology.
Again, this is an area where there's a lot of innovation spurred by legislation, but I would caution against this technology.
