They also illustrate the evolution of this protein: birds have no receptors for capsaicin, while mammals do. Birds eat seeds mostly intactly. Their digestive systems are capable of breaking them down - but it's stochastic and some seeds make it through the bird undigested, being redistributed elsewhere. Obviously, having an agent sow your seeds widely is a fitness advantage, and so seedy plants are ultimately served well even if 90+% of their caloric investment into seeds goes into the birds. Mammals, on the other hand, have teeth - particularly molars. Mammals that eat seeds grind them apart orally before even swallowing. As a result, any seeds ingested by mammals are very likely to be completely destroyed. Plants - peppers, anyway - found a chemical irritant that repels the mammals without even being sensed by birds.
However, we argue that even an incremental increase in AI capabilities, without any coordinated power-seeking, poses a substantial risk of eventual human disempowerment. This loss of human influence will be centrally driven by having more competitive machine alternatives to humans in almost all societal functions, such as economic labor, decision making, artistic creation, and even companionship.
Once this human participation gets displaced by more competitive machine alternatives, our institutions' incentives for growth will be untethered from a need to ensure human flourishing. Decision-makers at all levels will soon face pressures to reduce human involvement across labor markets, governance structures, cultural production, and even social interactions. Those who resist these pressures will eventually be displaced by those who do not.
