> With Terabyte (TB) RAM computers becoming the norm in the near future

I don't know in which world you live but in mine people still mostly buy 4, sometimes 8GB of ram laptops

I think he was talking about the clusters of machines used in big data. Both in processing (Spark) and storage (SAP HANA). These use cases can need TBs of ram.

These use cases can need TBs of RAM, but they don't get it in a single node but as a distributed system with tens of GB of RAM per node.

Um, err we have a few tens of 1.5TB memory nodes lurking around. There are plenty of use cases for that out there.
I work in a cloud environment where SAP HANA databases are provisioned. We offer VMs with multible TiB RAM for the larger HANAs.

Not only that, but those terabytes are actually distributed systems running at most a few hundreds of megabytes of ram in each node.

You can get a node with ~26.4TB memory on AWS: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/memory-o...
I suppose what one considers the near future is relative.
He is probably not talking about Macbooks
With multiple accounts and VMs running Linux, which in turn run a JVM and a heavy IDE, my Mac Mini is at 64GB, and it needs all of it.
