> "but in 3.5 years couldn't do the actual goal"
For a very long time, i.e. for a few years, the actual goal had been announced as planned to be achieved towards the end of 2025, when the CMOS fabrication process Intel 18A should become usable for the mass production of Intel server CPUs and laptop CPUs.
If Pat Gelsinger had remained the CEO of Intel, only in 1 year from now it would have become possible to decide whether he has been a good CEO or a bad CEO.
Now, after he has been ousted prematurely, nobody will ever be able to say with certainty whether Pat Gelsinger would have succeeded to redress the fate of Intel or not. Since he has become CEO, all the intermediate milestones towards the stated goal have been achieved in time, even if with various problems, which were nevertheless more or less predictable, because in the past Intel has never been able to do better than this when transitioning to new fabrication processes and new product architectures.
While he has diminished the earnings for shareholders, that was a very good thing to do, because before him Intel has wasted huge amounts of money by giving them to the shareholders instead of using them wisely to remain a competitive company.
Instead of looking at shareholder earnings, you should look at the revenues of the Intel employees. I do not know if this is true, but another poster on this forum has said that Gelsinger has given a raise after becoming CEO, attempting to correct the situation where Intel is well known as a company that provides inadequate compensations to its employees, and he had promised that he will try in the future to improve this. If that is true, it has been something much more valuable than attempting to please the shareholders who have lead the company towards losing its competitivity in the market.
