Thanks for such a comment. I was hoping for it. I'm no mason but I've seen some of them work in my house. You just need to live outside university to understand that "innovation" in masonry requires a bit more than a funny augmented reality setup.

Manual work is usually the result of thousands of years of practice. And masters in their job are truly masters. That is, they do things you can only understand when you have reached some of their proficiency. I'm sad many people do not appreciate the quality of the job they do because "it doesn't look that difficult; you don't need a phd to do it".

I'm very respectful of these people (except that when you need a professional, somehow, they're always hard to find and just never start on schedule :-) just joking)
