GM can secure whatever they want, they don’t have the talent or culture to do anything with what they secure.
At most, GM will purchase someone else’s electric car design to use their battery supply. Then they’ll hire a contractor to build and design the factory. Then all of the staff that build it will be part time contractors from a temporary workforce company. The end result will be a piece of faulty garbage that barely drives, with nobody in the company to blame for its failure.
Most likely, GM will sell these contracts to someone who can actually execute, and they’ll make a tidy 2% profit to continue their mediocrity into the next decade.
