Would love to see more Swift adoption outside Apple ecosystem because it’s truly the best language I’ve worked with; but the busted state of tooling and environment (Xcode, janky at best VSCode support) will need to be improved before it can ever escape iOS/macOS only orbit.
Getting to FSD is probably moving a lot slower than they hoped and it's looking more and more like it will be another decade (or multiple) until a self driving company can turn a dime of profit. GM doesn't strike me as a particularly innovative company so the idea of a decades long moonshot probably isn't very appealing to them.
The dragging / lying to regulators incident was bad but axing the founders / CEO seems like it would have been enough if GM were excited about the company long term.
