Pi market ... sure. ARM based SBC not so much. Just get one of the zillion Pi clones that have many advantages like speed, better PCIe, not using USB for storage/net, more ram, better perf/watt, NVMe, etc.

But normal people are getting Raspberry Pi's. Some people by using rpilocator and patiently waiting for units selling at MSRP to come into stock at official retailers, and impatient people by paying inflated prices to scalpers. But anybody who wants a Pi can, to a first approximation, have on today.

And not to beat a dead horse, but there's good reason to believe that this situation is temporary and that supplies (and prices) will stabilize sooner than later.

All of this "the market for Raspberry Pi is dead" stuff seems like pure hyperbole to me.
