No, it's an attempt to form an artificial moat by buying all the world's GPUs and memory.
I just bought 2 switches, 48 port 10GbE with 4x QSFP+ at 40Gb fiber. $110 each.
You can even get 24 port QSFP+ @100Gb networking devices for $350.
Yeah while ram and gfx is $$$$$, networking is rock bottom prices..
(new in terms of the most recent models, not just "something with X number of ports")
