This could be great.
There's a future where RAM makers tool up for this massively increased demand, then the AI companies go broke as the bubble bursts, so RAM is cheap as. So laptop manufacturers get on that and start making laptops with 1TB+ memory so we can run decent LLMs on the local machine. Everyone happy :)
RAM makers are not increasing their capacity. If AI bubble bursts we might see a momentary drop in RAM prices but it won't be dramatic. Return to "normal" is the best scenario I can imagine but my gut tells me we're probably never going back to early 2025 memory prices.
