Andrej Karpathy shares his experience with the recent explosion in AI agent capabilities. He describes experiencing 'AI psychosis' since December 2024, when his workflow shifted from 80/20 self-coding to 20/80, spending most of his time instructing agents rather than writing code himself.

• A fundamental capability shift occurred around December 2024 where code agents became sophisticated enough to replace most manual coding tasks
• The new bottleneck is no longer individual coding ability but managing multiple agents, optimizing agent instructions, and maximizing token throughput
• AutoResearch demonstrates that autonomous systems can optimize ML hyperparameters and code efficiency beyond what manually-trained researchers achieve
• Current AI systems exhibit significant 'jaggedness' -- superhuman at verifiable tasks (code, math) but primitive at nuanced or subjective tasks
• Digital work will be disrupted far faster than physical robotics because manipulating bits is vastly easier than manipulating atoms
• Education is fundamentally reshaping: experts should optimize for agent comprehension, creating agent-readable documentation that agents can customize for individual learners

Steven West explores Alasdair MacIntyre's 'After Virtue,' examining why modern moral conversations feel so unsatisfying. MacIntyre traces moral thought from Homer through Aristotle to the Enlightenment, arguing that the removal of teleology from moral philosophy has left us in an 'emotivist' culture where moral debates become exercises in emotional expression rather than rational discourse.

• Moral teleology (purposeful ends) was central to virtue ethics from Aristotle through medieval times -- virtues were bridges helping people move from who they are to who they could be
• The Enlightenment abandoned teleology to create secular universal morality, but this removed the foundation that gave moral concepts their meaning
• Modern moral conversations are incommensurable because we lack shared ends -- without agreement on human flourishing, philosophers can only talk past each other
• Emotivism describes our current moral landscape: moral claims are emotional expressions, not truth statements, making rational persuasion impossible
• MacIntyre proposes shared practices (farming, medicine, sports) as modern sources of teleology -- activities with internal goods and standards that allow communities to rationally evaluate virtue
