The question isn't whether AI doom is likely.
It's whether the expected harm is significant enough to act on.
Given the math? The answer is clearly yes.
We don't need certainty to justify precaution. We need responsible risk assessment.
(7/7)
This same risk framework (expected value of harm) applies to non-catastrophic AI risks too:
- Algorithmic bias
- Economic displacement
- Privacy violations
- Misinformation at scale
If the product of probability and harm that matters.

Most AI researchers agree existential risk from AI has LOW probability.
But low β zero.
And when we're talking about existential outcomes, non-zero probabilities require:
- Serious research
- Robust safety measures
- Contingency planning
(5/7)
en.wikipedia.org/wiki/Safety_...
We have precedent for this thinking.
Before launching the Large Hadron Collider, CERN seriously studied scenarios like micro black holes destroying Earth.
Did physicists think it would happen? No. But the potential harm was so large, they HAD to investigate. (4/7)
en.wikipedia.org/wiki/Strange...
If potential harm approaches infinity, only a truly negligible probability makes the overall risk acceptable.
Low probability β no risk when the stakes are existential.
(3/7)
en.wikipedia.org/wiki/Risk_as...
What matters is: Probability Γ Magnitude of Harm = Risk
When harm could be civilization-ending, even tiny probabilities demand serious attention.

The AI existential risk debate is often framed wrong. People focus on "how likely is this?" But that's not the right question.

Happy to present today our work on generative AI for RIR!
Dolby Barcelona Scientific Paper Award 2025 - deadline extended to 30th September due to ICASSP paper submission overlap.
Final call!
Details: professional.dolby.com/legal/barcelona-scientific-paper-award-2025/
Just 11 days left until the Sept 15 deadline and we've already received some excellent submissions.
Still working on yours? Don't wait: showcase your 2024-2025 sound research now.
New paper!
We're introducing a new way to generate realistic room impulse responses not from room geometry, but by directly controlling acoustic parameters like reverb time and direct-to-reverb ratio.

This work was the result of Silvia Arellano's internship in Dolby Barcelona with us.
Come explore the demo here:
π silviaarellanogarcia.github.io/rir-acoustic/
π Paper: arxiv.org/pdf/2507.12136
Feedback & questions welcome!
We explore 4 DAC-based models:
1οΈβ£ AR w/ cross-attention
2οΈβ£ AR w/ classifier guidance
3οΈβ£ MaskGIT w/ adaptive layer norm
4οΈβ£ Flow matching
The MaskGIT model achieves the best subjective quality (avg. 70 MUSHRA score), beating state of the art comparisons.
Instead of simulating room geometry, we train four different generative model to produce RIRs conditioned on acoustic attributes (T30, T15, EDT, D50, C80, source-receiver distance)

The key issue isn't the most likely outcome β it's the worst-case scenario we must be prepared for.

Just as nuclear research is subject to international oversight, frontier AI development should be too. We need strong global regulatory frameworks for models with potentially vast power.
