In my company, [enterprise IT] architects are separated into two kinds. People with a CV longer than my arm who know/anticipate everything that could fail and have reached a level of understandind that I personnally call "wisdom". And theorists, who read books and norms, who focus mostly on the nominal case, and have no idea [and no interest] in how the real world will be a hard brick wall that challenges each and every idea you invent.

Not being hands-on, and more important not LISTENING to the hands-on people and learning from them, is a massive issue in my surroundings.

So thinking hard on something is cool. But making it real is a whole different story.

Note: as Steve used to say, "real artists ship".
