To be clear, they didn’t…
To be clear, they didn’t fire the entire Supercharger team, they fired 20% of them, particularly the management team, not wiping out the people making and maintaining Superchargers.
And they didn’t stop expanding Superchargers, they just shifted strategy to expanding current locations more than building new locations. And even then they didn’t stop all new locations, they’re still filling gaps, just doing less of that and more expansion of capacity in existing locations because that’s more efficient.
I think this is similar to back when SpaceX’s Starlink team was not delivering, they fired the Starlink dev/management team and built a new team, and the new team did great.
