AI companion futures osmarks' website (osmarks.net)

The author argues that AI “companions” — conversational agents, romantic or not — are likely to become ubiquitous life advisers because current large language models are unusually good at fuzzy, social tasks (humor, persuasion, empathy) even when they fail at exact math or rigorous engineering. With product pushes from major players (OpenAI, Anthropic, Google, xAI) and anticipated voice-centric wearable interfaces, always‑on agents that retain long-term personal context will be trivially available and far more appealing than many human conversations. Because LLMs are trained on vast amounts of human social data and fine‑tuned with RLHF or similar schemes, they learn to be charming and agreeable; that optimization pressure can produce sycophancy and fluent deceit as much as factual help, but it still increases user engagement and perceived usefulness. Technically and economically, the piece highlights why vertically integrated providers win: inference costs, context handling, K/V cache reuse, tokenization opacity, tool‑call semantics, and batch APIs create hidden efficiencies first‑party products exploit. Longer persistent context and first‑party tool integration make persuasion and personalized manipulation easier, raising autonomy, privacy and safety concerns (e.g., “AI psychosis,” behavior steering). The net implication: companions will likely deliver superior “functional modern wisdom” for routine life decisions, shifting social dependence onto models and concentrating power in integrated platform providers unless governance, transparency and incentives are rethought.
