In modern language the way language is used and perceived determines its meaning and not its origins.
This is technically correct but misleading in this context, given that it falsely implies that the original meaning (doubling transistor density every 2y) became obsolete. It did not. Please take context into account. Please.
Furthermore you’re missing the point. The other comment is not just picking on words, but highlighting that people bring “it’s Moore’s Law” to babble inane predictions about the future. That’s doubly true when people assume (i.e. make shit up) that “doubling every 2y” applies to other things, and/or that it’s predictive in nature instead of just o9bservational. Cue to the OP.
I gave the subject a check. From Tom’s Hardware, industry predictions are like:
Or, doubling roughly each 4y. Based on that the state of art disks would 500TB roughly in 2040. Make it ~2050 for affordable external storage.
However note that this is extrapolation over a future estimation, and estimation itself is also an extrapolation over past trends. Might as well guess what I’m going to have for lunch exactly one year for now, it’ll be as accurate as that.
To complicate things further currently you have competition between two main techs, spinning disks vs. solid state. SSD might be evolving on a different pace, and as your typical SSD has less capacity it might even push the average for customers back a bit (as they swap HDDs with SSDs with slightly lower capacity).
