It is now more than two years since the first data from the James Webb Space Telescope were released. Webb's unprecedented IR sensitivity has revealed multiple surprises about the first billion years of cosmic evolution. Early galaxies and black holes were much more numerous than we imagined, and their properties are quite different from their familiar local counterparts. I will give an overview of Webb's most intriguing discoveries at cosmic dawn to date, and will discuss how these observations have modified our theoretical understanding of how galaxies and black holes form and evolve from the earliest times.
