LucidLynxHold on to Your Hardware
I don't buy the central thesis of the article. We won't be in a supply crunch forever.
However, I do believe that we're at an inflection point where DC hardware is diverging rapidly from consumer compute.
Most consumers are using laptops and laptops are not keeping pace with where the frontier is in a singular compute node. Laptops are increasingly just clients for someone else's compute that you rent, or buy a time slice with your eyeballs, much like smartphones pretty much always have been.
I personally dropped $20k on a high end desktop - 768G of RAM, 96 cores, 96 GB Blackwell GPU - last October, before RAM prices spiked, based on the logic that hardware had moved on but local compute was basically stagnant, and if I wanted to own my computing hardware, I'd better buy something now that will last a while.
This way, my laptop is just a disposable client for my real workstation, a Tailscale connection away, and I'm free to do whatever I like with it.
I could sell the RAM alone now for the price I paid for it.
The thing is, other than AI stuff, where does a non powerful computer limit you?
My phone has 16gigs of ram and a terabyte of storage, laptops today are ridiculous compared to anything I studied with.
I'm not arguing mind you, just trying to understand the usecases people are thinking of here.
3D CAD/CAM is still CPU (and to a lesser extent memory) bound --- I do joinery, and my last attempt at a test joint for a project I'm still working up to was a 1" x 2" x 1" area (two 1" x 1" x 1" halves which mated) which took an entry-level CAM program some 18--20 minutes to calculate and made a ~140MB file including G-code toolpaths.... (really should have tracked memory usage....)
Is that by convention or is there a good reason that it’s so CPU bound? I don’t have experience with CAD, so I’m not sure if it’s due to entrenched solutions or something else.
