[Panopticon Central via Rob Caron] They must have absurdly grandiose goals. Something like "fundamentally reimagine the way that people work with computers." Nobody, including the people who originate the goals, has a clear idea what the goals actually mean.
Interesting observations about black hole projects. Before coming to Microsoft, I saw a lot of similar traits with various companies in the mobility space who’s only vision was to "do everything, for everyone, at anytime". Of course, most of them are gone now.
But the one that personally kills me (and that I totally agree with): They must involve throwing our some large existing codebase and rewriting everything from scratch, "the right way, this time."
