We absolutely need experts who focus exclusively on product, on engineering, on policy — those demand high-quality, dedicated specialists — but we also need people — I've taken to calling them technologists — whose expertise cuts across those three domains. Someone needs to put the pieces together. Someone needs to navigate the digital world (for a business, a project, any institution) without blind deference to vertical experts, and without monkeying dumb Silicon Valley tropes or giving credence to breathless LinkedIn thoughtleadering. Someone needs to see the full set of options that is available to reach a goal, and that requires playing across these domains.
