"We do not need to understand how a brain works to know that it is intelligent." - Yann LeCun, AI pioneer
Limits of digital logic
Traditional software uses linear logic to trace errors. However, AI operates across billions of parameters in high dimensional spaces, making it impossible to pin down a single reason for a specific outcome. The internal logic is simply too complex for simple human explanation.
Trap of simple explanations
When we force AI to explain itself, it often confabulates. It provides a plausible sounding answer that humans want to hear rather than the actual mathematical reality of its decision making process. These linguistic translations are often just presentations of the truth. Some say that AI is simulating reasoning, though not actually reasoning.
Towards measurable outcomes
We should stop chasing interpretability and focus on observability. This means judging a model by its external behavior and results rather than trying to map out every single neuron's activity. This approach is already common in complex engineering systems we use daily.
Defining safety via guardrails
Like any advanced technology, we can set invariant truths or rules that AI must never break. By monitoring these risk thresholds, we can intervene effectively whenever these systems cross established safety lines. This ensures accountability through constant auditing and human intervention.
Building a trust foundation
Trusting AI requires us to accept that its internal logic is not fully knowable. Our governance should focus on rigorous auditing and performance evidence to ensure systems remain both useful and honest. Chasing the ghost of explanability only results in slower, less reliable systems.
Summary
Instead of demanding that AI explain its complex internal logic, we should focus on its measurable outputs. By setting clear safety guardrails and monitoring external behavior, we can ensure accountability without slowing down progress or accepting the plausible but fake explanations that models often generate to satisfy us.

Food for thought
If we prioritize a model's ability to explain its actions over its actual accuracy, are we intentionally choosing comfortable lies over complex truths?AI concept to learn: Mechanistic interpretability
This research field attempts to reverse engineer neural networks by identifying which specific neurons trigger certain responses. It involves a tedious process of trial and error to understand how a model maps high dimensional data into human language. While it provides some insights, it struggles to keep pace with the scale of modern model development.
