I agree with much of your vibe and attitude here. But in general while SR may not be rocket science, solving the problem of accessibility in a general and scalable way
is rocket science.
It's a really important problem, and a good cause. Disabled people, for example blind people, have an awesome contribution to make to society and we need their voices to be heard, so to speak. In other words, we need their contributions to be made. They must have access. But the question is how to go about solving that?
I think the posed solutions of getting every website to adopt a certain standard is not a good technical solution. I think pointing AI at the problem and working out how to parse accessibility hints, possibly in a personalized and contextual way relevant to the particular person as well, is one approach to the solution that's better.
This part,
I believe every developer who makes user-facing software should be forced to sit down and use their app/site with the monitor off, interacting with just the screen reader in their headphones
No, just no. I appreciate the desire to do good, but I think your attitude here is in danger of falling into the trap in this topic of being abusive to others under the mere guise of a "righteous cause" -- and in the process hurting the very cause you pretend to stand for. The misuse of this issue by some bully-like people who want to abuse others by trying to dominate them with criticism and control is one reason I'm so scared to engage with this topic. They use the seriousness of the issue as a fake pretext to case the world in their own self-serving and ego-serving view of good vs bad, and go nuclear on anyone who disagrees with their stance. But this is just ape brain shit of bullying for compensation to make themselves feel better by pretending others are worse....Just avoid that.
There is a serious issue here, and a good cause. And any statement that seeks to coerce or force or minimize the feelings of any group of people, who could just be working together on a solution, don't get suckered by the delusion that such things are somehow the right way, they're not. They're just people being bullies because their lives suck, and they take it out on others instead of fixing their own stuff. These abusive misusers of the issue give disabled people a bad name, and hinder the very cause they are pretending to stand for by, among other things, creating unnecessary friction to collaboration, and pushback.
If you care about this topic, maybe you can do some AI work on it.
