Wondering about a Theoretical Scenario [D]

So, let's say some random guy in the middle of nowhere finds or invents an algorithm leading to true AI* / AGI. What should that guy even do?

Making it open source would let absolutely anyone make AI. Of course, "anyone" includes both the most altruistic people on Earth and psychopaths hellbent on causing misery on others.

Making a research paper would be similar to making it open-source (I think? Correct me if I'm wrong).

Can't patent an algorithm I don't think.

Sharing the tech to a known tech company is like choosing open source but only the psychopath option (but for making money instead of causing misery; though the misery is implied).

Sharing the tech to the government would mean sharing the tech to a government.

Not sharing it all would mean that the tech might fade into obscurity. But it would also mean that, eventually, somebody else will just invent it again and fall into the same dilemma; and who knows what their morals will be.

* on true AI - It's just my opinion, but I think current AI just mimics thinking rather than being an emulation of the process itself.
