they are at least a 6th of the cost of a US person; the gap is even wider if compared to high cost centers.
Never going to happen, definitely NOT onshoring.
They could maybe close Chennai and expand Pune, or move to another low cost center, but there are zero rumors or truth to that also. India is already at capacity (space) in places, so closing one to make it worse elsewhere is pure fiction, or in this case maybe click-bait.
