Sad to see Gelsinger go, but despite the churn, I don't think Intel is doomed. At worst, per their most recent Q3 results, I see $150Bn in assets and $4Bn in outstanding stock, and I see the US Gov (both incoming and outgoing) gearing up for a long war against China where Intel would be an asset of national importance.
My back of envelope calculation says Intel should be about $35 a share (150/4). If they stumble when they report Q4, I think the US Gov will twist some arms to make sure that fresh ideas make it onto the board of directors, and perhaps even make Qualcomm buy them.
I do think that Intel need to ditch some of their experiments like Mobileye. Its great (essential) to try and "rebalance their portfolio" away from server/pc chips by trying new businesses, but Mobileye hasnt grown very much.
