Anyone expecting this product to do everything perfectly with 0 issues is out of touch. I'm actually relieved to see this, as it seems to be about the worst we've seen yet and there have been a few chances for such defects to come to light. I'd be more worried about a crumbling wall or something, but we haven't seen that yet and it's not something I'm worrying about (bricks and glue on concrete slab are old tech)

I'm happy we've been able to see these brick joints really up close, they really pack a lot of glue in and it looks like a very strong bond.

there are always going to be issues, especially with new technology. A small defect like this doesn't mean the concept is defective, just that there is some edge case or rare condition which needs to be handled through training, control, software or whatever.
