Anyone that's successfully been running hardware companies would be where I'd start. Offer the best of them much more money than they're currently making. Actually, hire a dream team of them. Turning Intel around would be worth paying a high price.
Maybe. It's a good start. The part where I'm unsure is that Cadence is one of the Big Three vendors. They have so much I.P., EDA tooling, patents, etc. that money will keep rolling in with incremental innovation.
Most hardware startups have to come up with new ideas, engineer good implementations of them, market them, and react to all kinds of competition. I'm talking companies like Habana or Cavium more than Cadence.
When I say hardware CEO, I meant one that ran a company like that where we know they'll be innovative and capable. Intel will need that since they're going to have to change so dramatically with so many product innovations. Whereas, running Cadence doesn't require (from what I know of them) that sort of innovation and it might have even hurt their entrenched position.
That said, I'm still positive about the new CEO. I hope his mindset and experience helps him do a lot of good. The letter he put out was great.
