Anyone who doubts...

Not sure where I read it, but a study was done that put the cost of a complete "wall" at $23 billion. Ironically the annual cost if defending it would be $23 billion per year. The real problem is not a technical one at all. No border defense is viable if it is unmanned and not maintained.
 
I'm not sure a physical wall is the answer. We have technology that might be as or more effective and probably a lot less expensive.
 
I just posted this because I thought it was a cool machine. The wall was an afterthought.
 
I'm always bothered by the one third overlap in block work. It doesn't allow the inner wall to take a load reducing the load bearing surface significantly. That's not the machine's fault though. It's the programmer.

That was interesting, but where is mortar to hold the bricks together? It's fast at stacking and placing the bricks in their proper place, but without the mortar it will fall apart.

That is very interesting, but it only provides a very narrow field of fire.

They make a model that is motion sensitive (and tracking) and when well hidden, you only need a few to get people attention and make them realize that it may not be worth attempting it.

Now that would be awesome to have near the border.
