The biggest issue here is that it hurts smaller consumers. Scaling up a fab to produce ram takes 5+ years, people generally buy new hardware ~5 years so this lifecycle of hardware for some people is now locked out. Let's say you was due for an upgrade this year you now might be priced out of the market for the next 5 years and basically due to poor business practices

There is a similar issue happening in the manufacturing space where metal foundries are basically "full" up on allocation for other customers and will refuse to sell to you unless your purchase order is six digits otherwise you pay a hefty premium which once again drives capital towards larger corporations. Compounded by a stagnant jobs market the means that scarcity is just going up and up and nobody is re-investing to meet consumer demands because the market is poisoned by speculation to the absolute extreme

Do people really still upgrade so often? I mean it made sense pre 2015 for desktops, and pre 2020 for laptops... But since... Not much has changed from a performance standpoint.

Even gpus hardly advanced since 2022 (4090) and the next generation is at least 1++ years off. Likely 2-3... And it's unclear wherever it will actually be an upgrade or more of the AI shenanigans they released with the 50 generation.
