Apple’s MacBook Pro memory problem is worse than ever

This is a most excellent place for technology news and articles.
Removing individual soldered NAND chips directly connected to the motherboard, attaching new NAND chips, and somehow getting a working computer out the other end is so far beyond the abilities of most users that it's not even funny.
It's way beyond the skillset of even most computer repair specialists too.
In fact, in terms of "getting it working again" is concerned, anyone outside of an Apple assembly plant is unlikely to be much use.
People have done it on M1's at least. You'll need a well equipped rework station to do it though, especially since the NAND is essentially glued to the motherboard in addition to solder.
