Downloading food - I suppose that when you download the food will pop out of your computer.
No cooking required
Prices no longer an issue
Eat what you want no matter who else wants it.
Food could be poisoned, similar to download viruses
Meats may be undercooked
Your keyboard is dirty. You'll have to wash your hands while your food gets cold.
You will not be able to find what you want for certain, and you may have to code it, which is more difficult than cooking
The economy would crash - computer food means all farmers, restaurant workers, grocery store workers, and/or any business related to food's workers would all be unemployed.
Could contain toxic material. If you wouldn't eat a computer without getting sick, and you wouldn't eat a printed picture of food without getting sick, what are the chances you can safely eat food that is similar to either printed pictures or something that pops out of a computer without getting sick.
3 pros and 6 cons. I say it would be bad.
