> that does not justify dropping the future innovation
Looks like they have mapped the possible paths and consider it a dead end. The density increase is low compared to the effort to process cost, so they just opted for a simpler process with a similar density at a much lower cost per wafer. They might come back to it at some point - they invented it and have substantial IP investment on it.
Also, there might be some cost of opportunity - the AI bubble is now, so anything that diverts from current extremely profitable product lines is a terrible idea. It’s a bubble and they have the fiduciary duty to suck it until it’s dry.
