How can you say that about the company that invented the 8042, 8048 and 8051 microcontrollers? These are likely the most sold microcontrollers ever up to this day. For example: The 8048 was used as the keyboard controller in every PC until USB took over.

If you mean that Intel has missed the 16 bit and 32 bit microcontroller market, then you are very right though.

Started a design in the middle of this pandemic. Used mostly China branded components (some datasheets in Chinese). China processor modules, external UARTs, IO expanders, transceivers. It's like a manual car design instead of a late model automatic :palm:

Recently Elon Musk said about how Tesla might got less affected by the chip shortage: "We were able to substitute alternative chips, and then write the firmware in a matter of weeks," and "It’s not just a matter of swapping out a chip; you also have to rewrite the software."

As any word from Musk has to be taken with a grain of salt, how would you say such a statement can be true? If he's talking of some accessory system, maybe ok, but if it's about some primary circuits related to the actual car driving system, wouldn't any change require a lengthy safety re-certification process?

They just pulled out the good old tool from the shed:

It's a corner-cutter.

Totally plausible.IMO Tesla is more vertically integrated than other automakers. There are hundreds of mcus and peripherals in a car, many not safety related
