Abstract  

In this talk I will review the ultimate goals and limitations of conformal bootstrap methods. In particular I will argue that to reach the bootstrap endgame it is crucial to work with improved tools for analysing bootstrap equations. I will argue that a complete set of such tools is now available for solving 1d CFTs: they are essentially version of Fourier transform for bootstrap equations known as extremal functionals. I explain why these significantly outperform traditional bootstrap methods and how they can be used for large scale numerical, as well as analytic applications.
