Kind of disagree. Have read on forums that by all accounts, the tech in the 18A process is amazing (Gate-all-around transistors, backside power-delivery, 3d packaging tech...), and that they are on the path to catchup/pass TSMC in terms of chip-fabrication performance/power-expenditure in a year or two. Yeah, this is an amazing achievement for such a large company.

But have also ready that to make this profitable is like a 5-8 year plan, not something that is profitable in 3. To me, this is his biggest mistake, he needed to keep the ship sailing at least somewhat smoothly while waiting for this big gamble to pay off.

And eventhough I do agree with you that he made a lot of mistakes, still he got the the most important issue right, regaining manufacturing leadership.
