I can't honestly say that it is my experience that organized religiosity seems to conduce much to either sanity or good conscience in those who make a big deal out of it, but I'm more or less content to say everybody should believe whatever they need to believe to get them through the night, at any rate until their beliefs start playing out in misleading, violent, or exploitative ways in the world.
The same is true of the fanciful faiths of the techno-immortalists, extropians, singularitarians, transhumanists, and other assorted superlative technocentrics, certainly.
By all means, Robot Cultists, cult robotically away to your heart's content, let your futurological freak flag fly.
Just don't try to peddle your Robot Cultism as
 constituting a novel, coherent, and systematic philosophical viewpoint; as
 advocating a unique, coherent, and needed political program; as
 contributing somehow to scientific knowledge or useful technique; or as
 engaging in serious public policy deliberation.
Otherwise, you know, let a bazillion blossoms bloom, and so on and so forth. I mean, after all, who cares?
