I don't think anyone thinks that? Unless you are trying to do local inference with bigger models, which isn't everyone's cup of tea but I do think is an important capability.
Outside of that use case though, prices are still ridiculous. 32GB of DDR5 will run you close to $500 right now vs. $80 before the AI build out, and 32GB is what I'd consider comfortable so long as everything keeps being electron and web wrappers (assuming Windows & macOS here for the general population, obviously you can get by with less on a Linux desktop for the most part).
Personally, I'd love to see more software do more with less, and go back to performant native apps but in reality I just don't see that happening, except maybe over here in Apple/macOS land which has always had a decent culture of native apps. For now, the incentives aren't there (for commercial software).
I hope you are right on prices, but I don't share the optimism. We've seen time and time again that once prices go up, they don't always go back down even when the supply crunch is eliminated. Manufacturers realize people adapt to whatever "new normal" prices are at and refuse to lower them. Same thing happened post-COVID supply shocks. Companies have zero incentive to start a price war, even after supply shocks are over.
I think we are stuck with ~$500 RAM for a long time.
