2. AI safety research attempts to mitigate some AI dangers.
3. Therefore we must fund AI safety research.
Yup, checks out.
The priests say virgin sacrifices pacify the gods.
Therefore we must sacrifice a virgin on every new moon. While we are at it, we should also build a palatial mansion for the wise priests.
Yup, checks out.
An argument that depends on equating priests and scientists is an argument that fails.
Edit: for instance, here's a computer science professor and neurologist who published a serious book about all the dangers of AI, and calling for funding safety research:

Furthermore, AI safety programs are hiring actual AI researchers and computer scientists to actually do the work, so are you claiming that these people don't sincerely believe in the work they're doing?
We must do something.
This is something.
Therefore, we must do this.
