I didn't say "wider". I said more subtle. It doesn't take much mathematical intuition and training to understand the rationals versus the reals. Understanding the computables versus the reals is a lot more tricky and takes a lot more thought. The simple arguments that show the difference between the rationals and the reals require a lot of very careful adjustment if you want to translate them to the computables versus the reals.
I agree the gap up to the reals is still bigger than rational -> computable. The reals are weird. This is a meme but there's a lot of truth in it: https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd.it%2Fnumber-systems-be-like-v0-xstowwchiexc1.png%3Fwidth%3D640%26crop%3Dsmart%26auto%3Dwebp%26s%3D249eada48d0423957f0030ae0e5a219ab9a0b0f9 https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd....
