Eh. I still hold to my favorite conspiracy theory:
1. Create a super effective vaccine.
2. Give everybody ample opportunity to take it.
3. Release a variant of the disease with a super high fatality rate and kill off the unvaccinated.
You could wipe out 15-30% of global population that way. It's a win-win for the environment, reducing consumption, and combating climate change while getting rid of excess people. If Bill Gates were actually smart and behind some grand conspiracy, that would be what he's doing.
