Recently, we have computed several quantities to five-loop accuracy in QCD, including the beta function and the Higgs decay to gluons. In this talk I will discuss these results and sketch several techniques to compute Feynman diagrams to five loops, such as integration-by-parts reductions and the R* operation. Finally, I will argue that more development on the computer algebra front is needed to further high-precision calculations.
