Practically, does this mean that cheap consumer electronics junk (think Bluetooth speakers, or streaming sticks, or cheap Chromebooks) will become scarce soon?

IDK! I wish I had some better idea because there is money to be made at least in options I think.

On one hand, I hope that cheap landfill-express electronics take a hit.

On the other hand, I’m well aware they will manage somehow and it’s the good stuff that will be hard to find/make.

For one thing I am certain, we absolutely have not seen the height of the supply shortage bullwhip. It’s going to get worse.

I'm seeing the > 52 weeks for every microcontroller I'm using in designs including old 8051's and MSP430's.
