Even though current VR/AR interfaces are completely useless for Excel or other data-management tasks (no keyboard support, unreliable controls, lack of development interest), I think in the future there are more embodied / spatial treatments of data access that could feel like an improvement on '2D' Excel.
As the author mentions, the original moniker for Excel was VisiCalc - a visual calculator. There's no inherent reason why 3D spatial representation would be a worse medium for a calculator.
