How come Trump doesn't talk about building his wall anymore?

When Trump was running in 2016 he promised to build a big beautiful 30 foot high brick wall across the entire US border.
But that brick wall turned out to be fence that Trump claimed was un penetrability.
But it turned out that that fence could be cut threw with a $10 hacksaw or pried apart with a 5 foot long pry bar. And the fence was only a couple of hundred feet long.
I figure if Trump used all the money he spent on the wall to hire more border patrol it would have been more effective. Cheers and happy weekend!
