You're wrong on so many levels.
First, you assume that 'one-way glass' means 'one-way mirror'. For all we know, they mean 'optical frequency circulators' which use ferrimagnetic crystals, and can definitely let visible spectrum light only way. Look it up.
Second, even for one-way mirrors, the term 'one-way' is appropriate enough. Few things in the real world are 100%. City streets, diodes, etc... we refer to them as one way, even when they really aren't 100% one way - the random car/particle gets through.
Third, we're Engineers. It's about getting results. We invent things that don't exist all the time. Although in this case, I doubt there are as many applications as the original article wishes they were. In a lot of the cases, you will get cheaper results with conventional soundproofing, and if you need the sound on one side, you can get it there with some good old microphones and speakers.
And even fourth. It's good to be looking for new stuff. You never know what's under the rock you turn over, just because it's there. You may be looking for a new way to turn lead into gold, and discover porcelain instead.
