As I pointed out in my other note, this is not true. The Java syntax
does not give human programmers control over pointers or memory
management. But the binaries produced still have pointers and memory
management. It is just that they were programmed into the Java runtime
system programmers rather than the Java source code programmers. This
just moved the problem, it technically didn't solve anything.

This is an important point! I hope that all AI developers are aware of
and are using all these formal program verification techniques.
Friendly AI cannot be as unreliable as today's typical commercial
