I really agree with your statement and people forget, but the reason third world countries are able to buy devices is because they are cheap, increase the ram price and thus every computing device and I think it will impact everyone of us but disproportionately due to power purchasing capacity and other constraints in an economy
I genuinely hope that this ram/chips crisis gets solved ASAP by any party. The implications of this might have a lot of impact too and I feel is already a big enough financial crisis itself if we think about it coupled with all the other major glaring issues.
Based on the article, demand exceeds supply by 10%. It seems that companies are taking advantage of this gap nothing else. I won't be surprised if the demand is kept this way for a while to extract profits. GPUs saw a similar trend during crypto. Then there were affordable GPUs at one point.
Old devices work just fine. I've upgraded my old iPhone XS last year to the latest and greatest 16 to see what changed (not much), the old one was still fast (in fact faster than a most upper-midrange Androids, its insane how much of a lead Apple has) and the battery was good. I considered selling it, but quickly had to realize it was worth almost nothing.
Also, when treated right, computers almost never break.
There's so much hand-me-down stuff, that are not much worse than the current stuff, that I think people even in the poorest countries can get an okay computer or smartphone (and most of them do).
