Even if the majority of people are unable to do these part-replacements themselves, it is still a massive improvement to make them easy to perform. The reduction in expertise required to perform these replacements would significantly reduce the cost of these operations while simultaneously reducing e-waste.

Additionally, the brain tends to adjust to a faster talking speed very quickly. If I'm watching an average-paced person talk and speed them up by 2x, the first couple minutes of listening might be difficult and will require more intent-listening. However, the brain starts processing it as the new normal and it does not feel sped-up anymore. To the extent that if I go back to 1x, it feels like the speaker is way too slow.

Agreed. However, by imposing tariffs it is not the privileged who are going to be affected the most. The pain is felt most by the low-skill workers you mentioned earlier.

If the solution was instead along the lines of changing tax-brackets to tax the 'privileged' more, that might have better addressed the problem you mention in the beginning.

"Tenacity is a most underrated quality in life. We all speak about talent, intelligence, glamour. But tenacity is the common thing for every successful person in life. Maintain that motivation to go from A to B and to keep your focus on that target without any weakening. That is called tenacity; stamina in your motivation." - Arsene Wenger (Legendary Arsenal FC Coach)

I would find this very useful on a site like Wikipedia where I often know the section I want to jump to before landing on the page. (e.g. I want to see the number of goals Messi has scored each season at Barcelona and I know there's always a table at the bottom of most wiki articles regarding historical stats for soccer-players). I could see from the mini-map where the tables are jump straight to it.

Like you said, the the text is too small to make out where you're going or navigating. But most often I find myself visiting sites that I've visited in the past and for those I have a good mental image of what the page already looks like. I can use the hints from a minimap to jump to the relevant section of the page.
