I do not see that happening in my life time. Modern society values none of the things that would help people with ADHD -- relaxed deadlines, less emphasis on productivity, valuing human lives over profits, etc.. Maybe someday in the future AI can take much of the burden off us, but till then, I only see things getting worse.
Yeah, I wouldn't expect that modern society is going to value things that would help people with ADHD. One might hope that modern society might value people with ADHD, at least enough to help them some. It's not like society's expectations of people don't change over time. They do.
That said, my statement that "we could be doing so much better" wasn't really a hopefully statement. It was more a statement of fact, and a recognition that society's expectations are killing a lot of people with ADHD.
