This is just pure greed. There is a memory chips shortage and it’s partly due to high demand, but at the same time the manufacturers trying to squeeze as much profit they can while the demand last without investing on increasing the manufacturing capacity. Apple already have such high profit margins and I’m pretty sure the next iPhones would be priced 100-200$ extra
Prices are never going down, even if the shortage eases. The era of cheap high-end computing is likely over. And it'll be used to pressure people into switching to thin clients and ever-more subscriptions High-end desktops were already a niche market, with many home users just using phones+tablets as their main devices. The entire games industry is already in a big crash too, and with consoles approaching $1k for 6yr…
I'm pretty sure prices are going down. Maybe not complete builds in nominal dollars, but $/gb for things like RAM and SSDs will be lower in 5 years than it is today almost certainly.
