Perhaps because our best-and-brightest are building this instead (boldface mine):
What’s a “pancake selfie” truck? Holiday Inn describes it thusly:
The rolling pancake station is outfitted with five pancake machines, each producing one pancake per minute – all at the push of a button. One-of-a-kind laser printers then transfer selfies from smartphone to pancake. From batter to platter, the entire process takes mere minutes. This delicious piece of breakfast technology was created and perfected exclusively for IHG and is a first for any hotel brand.
It’s not clear this is any more productive than porn.
I got nothing.
