After what, over a month of setup? Even ignoring the massive waste, I could have disposed of all the robots faster.
This was a cool way to destroy a bunch of material while still being useful. It's a cool ad and they can sell the smelted stuff as whatever trinkets.
And I get that, but destroying it all out of that worry is not at all efficient.
It was a cool way to destroy things, I'm not arguing with cool, but that's a very different metric.
