I did punch cards my freshman year, then the school converted to terminals.
At the end of the first semester I recall seeing an upper classman carrying a large deck (probably 300+ cards) to drop off at the computer center. At that time we wrapped our deck with a couple of sturdy rubber bands and dropped them in a slot. At the beginning of the semester we could return in 1-2 hours to get our deck + printout. At the end of the semester it was 12 hours. This enforced reviewing the code and NOT making mistakes.
Anyway, the upper classman dropped his deck and the single rubber band he used broke. Cards scattered all down the hallway. He looked like he was going to cry, started to pick up his card, then turned and walked away.
The morals of this story? 1) use more than 1 rubber band. 2) use a wide marker to draw a diagonal stripe across the top of the deck to the cards can be re-ordered visually.
On the other hand, early 80s systems were complete development environments which presented themselves with no introduction and no serious booting (you can even run a commodore 64 in a browser). You were alone with the intro screen

I agree it is a useless IoT, but part of me saw it and thought that would be a cool DIY project to play around with in my spare time.
Like what else could you make it do? Have it display a list of unsecured networks as you walk around town? Or have it look for discoverable devices on the same network and pop up a 'Hi [device name]! I can see all of your dirty pictures!' message... just don't have it display any of those images.
