Ono sto mene brine kod cijelog tog "brave new worlda" jest (ne)dugotrajnost elektronike. Sto će se dogoditi kroz 3-4 godine kad počnu rikavati te consumer-level elektronike (ili cisto postanu zastarjele).

Worn-out NAND memory chips can cause a whole host of problems with some Tesla cars, ranging from the failure of the rearview camera to an absence of turn signal chimes and other audio alerts. Some 159,000 Tesla Model S and Model X vehicles built between 2012 and 2018 are at risk. These all use an infotainment system powered by Nvidia's Tegra 3 system-on-chips that include 8GB of eMMC NAND storage, which is typically found in phones and cheap laptops. The trouble is that these flash chips are wearing out, having hit their program-erase cycle limits, and are unable to reliably store data, causing glitches in operation. The storage controllers can no longer find good working NAND blocks to use, and thus fail.

Tesla seems to be well aware of the potential issue of eMMC flash wear and has provided firmware updates to help mitigate the problem but they are probably just delaying the inevitable for owners of Tesla autos which feature Nvidia Tegra 3 chips with built-in eMMC flash. The flash memory has in most cases simply reached its program-erase cycle limit and has started to throw up errors or stop certain functions from working.
