I don't know why you're inserting HN into it? We're talking about average people, not nerds with ad-blockers. Are you suggesting that the average person enjoys being interrupted with ads?
> It isn't the case that the average person's experience with today's internet ads is that of having their "... mind erode[s] into a twitchy mess."
Perhaps I was a bit dramatic with my wording, but my point still stands. Since you're flatly denying it, perhaps you have some references? As far as I can tell, all signs are pointing to widespread ADHD increases correlated to computer use, which may not be directly tied to ads exclusively, it stands to reason that they're big offenders given their nature of being short, attention-grabbing, context-breaking, non-interactive engagements. There's plenty of studies that support this.
> The average person doesn't look at the comment section of a nice YouTube video.
Um, really?
> Most people don't suffer — at least not consciously — as a result of ads.
My point was it's death by a thousand cuts, boiling the frog, etc. The average attention span has been cut in half over the last 20 years. Also, I'd argue that sensitive people who may already be mentally stressed, which seems to be a growing group, might actually suffer in the short term or immediately.
You've made some strong statements, but I'm having a hard time buying them.
