But if you ask the people that would actually consider external RAM, I think you'd see a lot of awareness.

If there's a reference I'm missing, enlighten me...

Anything to do with data processing, machine learning, llms- hundreds of gigabytes of ram can be incredibly nice.

Especially as pandas recommends ram equal to 5-10x the size of the dataset.

When you're an individual- not having to think about managing a cluster...

It's the classic Bill Gates quote taken out of context where he says that 640kb ought to be enough for anyone.

This wasn't mentioned in the article but CXL Stands for Compute Express Link which is an open standard, CPU-to-Device Interconnect, I guess they're on v3.0 now. First I had heard of it as well. 3.9GB/s on the low end and as high as 121.0GB/s with the latest 16x 3.0 spec over serial connection
