Brian Halligan(@bhalligan):I cloned myself. Meet v2 of Hal = my second brain and AI human (digital twin) He is 10x better than v1, which we posted a few weeks. Smarter. Faster. More me. For most of my career, I chased developers to help me build something. For Hal, I did it myself. I stayed up until 4 am several nights building the core brain, connecting all the tools. Having total control over the context and architecture was the most fun I’ve had in years. He is an actual presence in my meetings and remembers more than I ever could.
