For example design &#x2F; civil engineering. Unless we can adjust literally everything to be supported by arbitrary-width any-direction conveyor belt system, we&#x27;ll have issues with transport. Unless we can easily sell devices that are adaptable to any body shape&#x2F;position (this goes from &quot;screen for fat fingers&quot; to &quot;can&#x27;t reach the panel on the wall&quot;), we&#x27;ll have issues with interfaces. And so on - this applies to thousands of ideas.<p>We already see those 2 problems right now: Existing issues about how to handle people who don&#x27;t fit in economy seat on a plane without disturbing the next person. Smartphone (and previously calculator) design doesn&#x27;t work for people with bloby fingers.<p>We barely started to make essential services available to disabled people who don&#x27;t actually have a choice of moving on their own, or read, or... If we can&#x27;t handle that special case, I don&#x27;t think we can easily handle those self-inflicted issues as a norm.
