Look, I know that cooking rice isn’t rocket surgery, but cooking it in a pot still requires you to babysit it to an extent, otherwise you end up with burnt rice. A rice cooker is the same process, except you can literally fire and forget it and come back when you’ve cooked other stuff for your meal and you’ll have perfectly done, warm rice waiting for you. As a person with ADHD, anything that reduces the mental load and reduces the demands on exact timing is good for the success of my endeavors. Plus you can cut up some veggies and slam them in the steamer on top for more bang for the buck (I don’t know if all cookers have those, but ours does and it’s great). You can set all that up, make some beans on a pan, add seasoning and you have a quick, healthy, filling meal with very little demand on executive function while making it. Idk I just like having it a lot ¯\_(ツ)_/¯
