Why can't Tesla's MCU 2 chip be upgradeable to MCU 3???

[Safemaster20]

This is sad because tesla owners who bought their Tesla's in 2021 have the MCU2 chip which is not up-gradable to the MCU3
They have to find a solution for this issue. Now that the zoom app came out I can't get it, or other apps that come out only for the MCU3.

technically they are upgrade-able but it just too costly for them to do so, besides there will be better hardwares later on, so no point upgrading MCU3 maybe there will be 4 or 5 but they need to make it upgrade-able sooner or later, at least when MCU 4 comes out.
they shouldve planted out earlier by using thicker gauged wire and add some additional wires for 15v ion.

they probably will end up upgrading those hardware for FSD users because MCU and HW are in a unit or face another someone will sue. (suppose)
MCU2 and 2.5 FSD user will need a HD radar upgrade see what will happen..
i want to play a decent game too

lastly they have not update nor improve wiper and matrix headlight.
i saw the other day a BENZ with multibeam LED in USA working flawlessly...
