Use a normal keypad safe whose code you can change.

Every day, post a puzzle whose solution is the code to the safe. It's a lot more flexible than a safe that he hacks once and is done with.

You can also vary the puzzle's difficulty by his level. So start off easy (57 x 23) and get harder (what's the last olympics whose year was also a square number?)

Or if that's too math-y, you can do something like "A hacker left a note in ASCII: 50 48 48 48. Decode the values to find the 4-digit number"

Depends on the terrain, as a clear field is very different than a dense jungle.

The best strategy is to harass the gorilla so it can't eat, drink or sleep for a while.

There's a course at Texas A&M for undergrads, and there was one at UT but I don't know many more.

My reasoning given how you phrased the question:

What's the largest animal that you think you can take in a fight?

I wrote a whole chapter about this in Fiat Ruins Everything about how Fiat Money has ruined Science. For example, the entire "science" of climate is driven by political considerations through grants, which, of course, is driven by fiat money. What's surprising is how slow scientific progress has been because of how politicized it's become.

It turns out that truth does not give itself up very easily, and anything less than a complete and dogged pursuit of it will fail.

I suspect it's because free trade is a pillar of the WEF/globalist agenda and has been for at least a generation.
