You've used reasonable twice, but haven't explained how it's reasonable.

So let me get this right: It's okay for a blind person to write content about accessibility being trash, but it's not okay for a privileged person without disabilities to share that content.

I'm not sure how that's supposed to be a reasonable point of view. Keeping the problems nicely hidden from the larger community is not going to help anyone. Of course merely talking about a problem isn't going to solve it either, but it's more likely to lead to solutions in the long term.

Aren't discrete and discreet homophones?

I'm very confused, the author talks about having to charge a device instead of replacing batteries and blames it on Lithium-ion batteries, instead of doing the sensible thing and blaming it on devices with non-replaceable batteries.

The form factor of AA and AAA batteries (which the author prefers) exists with all kinds of chemistries, including Lithium-ion nowadays, you can recharge them, but while you are doing that you can also put new batteries in your device and use it immediately.

> Q is indeed dense in R, but firstly it’s very clear that there isn’t an equal number of them because rational numbers are a subset of the real numbers and there exists at least one irrational number (I pick “e”) that is in R but not in Q. So R must be at least bigger than Q.

This isn't a correct explanation, because I can use the same explanation to show that there are more integers than that there are even integers.

"it’s very clear that there isn’t an equal number of them because even numbers (let's call it E) are a subset of the natural numbers (let's call that N) and there exists at least one odd number (I pick 1) that is in N but not in E. So N must be at least bigger than E."
