There are numerous companies taking bids to build The Wall. Now most of these are construction firms as you would rightly expect.
The problem is that this is also supposed to be a high tech wall. That means software.
Hey guess where the companies sending out those bids are based?
Did you say, San Francisco? Good boy! Here's a biscuit.
There is always the possibility that there is a right-wing incubator in the Valley. Who knows right? I mean anything is possible but the question that has to be asked is can any of those software companies be trusted to do the job without sabotaging it?
