This is another attempt, also looks credible:

The unification of all fundamental forces: A spectral approach.
Shane Farnsworth
Perimeter Institute
One major outstanding quest of modern day physics is the complete unification of all known forces. In this talk I will describe one possible approach to unification: that of ‘Non-commutative Geometry’, in which all forces are described as resulting from gravitational interactions on a ‘non-commutative’ space-time. Using this approach it is indeed possible to describe Einstein gravity coupled to the standard particle model in all of its detail. The ultimate goal of the talk is to introduce my own research, in which Non-Commutative geometry is extended to describe non-associative spacetimes. arXiv:1303.1782v2
