We discuss how 3+1-dimensional physics including gravity can arise in the IKKT or IIB matrix model. The model is related to string theory, but it also provides a direct and accessible definition of 3+1-dimensional physics on suitable backgrounds. This leads to a higher-spin extension of gravity on covariant quantum space-time with manifest volume-preserving diffeos, which is UV finite at one loop.
