Deepfakes are already being used in political manipulation. The success of the bullshitter, and Republicans who pressure each other to believe even obvious lies, has made the US more vulnerable to them.

The hypothetical deepfake described at the end of the article goes only a little beyond what the bullshitter has already hinted at.

Seawalls to Protect US Against Rising Oceans Could Cost $416bn by 2040.

That spending would be as futile as trying to bail the water out of the ocean. By 2070 we would need to spend another 400 billion, or perhaps another 800 billion or 2 trillion, because (1) the cost of each cm of sea wall increases as it gets taller and (2) sea-level rise will accelerate with time.

We can't afford to cure this problem. The only remedy we can afford is to prevent it.

The US government argued in the Supreme Court that it has the power to imprison anyone forever, including even US citizens, simply by asserting that perse is planning terrorism.
