Erm, let's be a little defensible here.
These sensors have to be stored in sterile packaging--that means thick enough to be a barrier. That means it also has to hold the sensor in such a way that a palette can be gamma irradiated. It also needs to be resistant to drops, crushes, and other accidents.
The sensor has to not be harmful with organisms irrespective of the understanding of the person using it. Any change to that packaging has to be re-evaluated for effects on that sterilization.
And while I understand people having concerns, if the only reason we needed to use plastic was to treat folks with diabetes--I think the world would somehow manage.
Remember, most Hieroglyphs had two or three consonants, and there was no Ancient Egyptian "alphabet", that is something they made up for tattoo's and tourists. When you wrote something in Egyptian, you didn't just combine a bunch of characters that each had a single consonant sound, that was an innovation of the semites. Then later the Greeks come up with the concept of vowels.
Apart from being shaped vaguely like a house, another clue is in the name. Semitic B's have a name that means house.
I don't know too much about this, so I definitely could be mistaken, but the professor seems to say this hieroglyphic may be connected with our current letter "B". Also, I think he said something about "house" on another video and I believe it was different.
