Region-specific weighting of sensory intensity and reward prediction error by dopamine signals
Growing evidence shows that dopamine signaling is diverse, with dopaminergic neurons responding to rewarding and aversive stimuli. Here, we hypothesiz…

I honestly think LLMs are very useful tools, but this kinda shit shows the real danger with these models: Stupid people with important roles will use them for purposes they are not well suited for.

Reminder: They're trying to demoralize you, and they're doing a great job of it. Part of resisting is making time for joy despite the attempts to make you feel this is not the time for it. Love your people. Dig the art that speaks to you. Go to the places where life flows into you. You deserve joy.
