It's feel just the next evolution in our written messaging dialect. Gen X had c u l8r?. Millennials didn't have to pay per character, and got full qwerty keyboards so opted for normal sentences. And now Gen Z have decided that auto-capitalisation is unnecessary.
I actually didn't notice the lack of caps until I read this comment
I also didn’t notice the lack of caps until coming to the comments.
…and I’m a pedantic SOB!
At least make it sound like you’re speculating if you’re going to.
Protein-wise, an all cabbage diet would give you more if you’re meeting calorie needs - 5.1g protein per 100 calories, or 102g protein for 2000 calories worth of cabbage.. but that is a heck of a lot of cabbage (17ish lbs)!
Let’s be real though, people should be eating a varied diet and not just a single food. And perhaps not a junk food only diet.
When I was growing up, there was a vogue among my fellow vegetarians for the book Diet for a Small Planet which suggested that we needed to eat a diversity of amino acids in each meal, hence "complementary" proteins at the same time. This concept then seemed to fade away completely because it appears that the body can actually successfully make use of amino acids even when consumed at different times. But they have to be consumed eventually!

The rationale there is a combo of profit (from off season strawberries) and mark-up possible from unique branding (Dyson) and social fuzzies (eco-friendly, etc (regardless of cold economics)).
Potatoes especially don't like to be submerged. But otherwise they are not that hard to grow. A simple grow bag will do. That's true for a lot of root vegetables and tubers. For vegetables like that, greenhouses are more common.
With rice and grains, they grow well enough in hydroponics but you just need an enormous amount of area to get to interesting amounts. Also the growing season for that is quite long. Hydroponics favor things that you can harvest in weeks rather than say 2-3 times per year.
I'm more intrigued by duckweed, which grows very fast and is a common food in some countries.

So the alternative is to grow lettuce that has a greater price to energy ratio.
Other nutrients like phosphorus or potassium come disolved in water, but in intensive farming they must be added to the soil, so it's the same that dissolving in the hydroponic solution. Perhaps it's more efficient in hydroponic than in soil.
Nitrogen is more tricky. There is plenty of Nitrogen in the air but not in a useful form, so in most cases it must be added as fertilizer. In some cases like soy the plants have helper bacteria that transform the nitrogen from the air into useful forms. This conversion takes a lot of energy, so I don't expect the lack of wind to be a problem, you still need some air movement to keep the CO2 high and the O2 low. (Anyway, farming soy under artificial light is probably not profitable for the same reason farming potatoes under artificial light is not profitable.)
The most important thing you lack inside a vertical farm that you get almost for free in a big faring field is sunlight (i.e. energy).
Bioflavonoids are important.
