What it is
Numberphile's hour-long conversation with Berkeley mathematician Edward Frenkel about the Langlands Program, often described as a grand unified theory of mathematics. He explains how it links number theory, harmonic analysis and geometry, and how it relates to results like Fermat's Last Theorem.

Numberphile published an hour long video [1] about the Langland program, which dives a bit into this "grand unified theory of mathematics". I'm not a mathematician, but I find these topics fascinating. [1] [this video]

Langlands is a massive programme but originated with Langlands conjecturing in 1967 about some deep connections between two seemingly unconnected areas of mathematics (number theory and harmonic analysis). In particular, he started with what was then called Taniyama-Shimura-Weil conjecture which concerns the number of integer solutions to particular types of equations of elliptic curves following (for no immediately obvious reason) a harmonic series. Wiles’ proof of FLT proved a special case of TSW and involved techniques which some of his students then used to prove the TSW conjecture in full generality, so is now called the “modularity theorem”. In fact the Langlands programme began with L

The Langlands program is about correspondences between analytic number theory and harmonic analysis. You could think about it as a unification of parts of mathematics that seem to have no reason to join up but turn out to have deep and non-obvious connections. It doesn't have anything to do with formalization. Here's a really good and accessible intro to Langlands [this video]
