The people from @CosicBe@twitter.com publish talks regularly. I recently saw "Full Domain Functional Bootstrapping Towards Practical Fully Homomorphic Encryption" by Leonard Schild #FHE #TFHE #FDFB #LWE and #RLWE; I like to share it https://www.youtube.com/watch?v=7KuFCYme38g. Yes, there are maths behind and in the slides, but the fundamental concepts can be followed in the explanation without needing to understand the details.
