AI Agents, Data Models, and the Post-Literate Engineer — with Joe Reis
AI agents can consume more information than ever. That doesn't mean they understand your data. For the Season 1 finale of Domesticating AI, we're joined by Joe Reis, co-author of Fundamentals of Data Engineering , for a conversation that went somewhere completely different than we planned. We start with Joe's practical take on local AI. If subscriptions to frontier models are cheaper than buying hardware, when does self-hosting actually make sense? Privacy, IP, fine-tuning, and inference costs at scale all change that calculation. Then we get into data modeling. Humans are remarkably good at working around bad schemas, missing documentation, tribal knowledge, and ambiguous business definitions. Agents aren't. If machines are going to operate on our data, the structure, relationships, provenance, and meaning of that data become much harder to ignore. From there, things get weird. We talk about corporate knowledge bases, ontologies, the post-literate engineer, AI-generated summaries, whether engineers still need to read the research, and the increasingly shaky state of reproducible AI benchmarks. Topics include: • Local models vs. cloud AI economics • Bonsai 27B and 1-bit models on phones • Data modeling for AI agents • Knowledge bases and organizational knowledge • Ontologies and semantic modeling • The post-literate engineer • AI summaries vs. actually reading research • Reproducibility and AI benchmarks • Why agent security doesn't require Skynet to be dangerous Links mentioned: Joe Reis — The Post-Literate Engineer https://joereis.substack.com/p/the-post-literate-engineer Joe Reis — Practical Data Modeling / Mixed Model Arts https://practicaldatamodeling.substack.com/ The Mixed Model Arts Manifesto https://practicaldatamodeling.substack.com/p/the-mixed-model-arts-manifesto Fundamentals of Data Engineering — Joe Reis & Matt Housley https://www.oreilly.com/library/view/fundamentals-of-data/9781098108298/ PrismML — Bonsai 27B https://prismml.com/news/bonsai-27b DeepSeek V4 Flash https://api-docs.deepseek.com/updates/ William Kent — Data and Reality https://bkent.net/Doc/darxrp.htm Find Domesticating AI: YouTube https://www.youtube.com/@DomesticatingAI Apple Podcasts https://podcasts.apple.com/us/podcast/domesticating-ai/id1873338950 Spotify https://open.spotify.com/show/2WsAR4fvcXzp3vVZGVlkE2 Patreon https://patreon.com/DomesticatingAIPodcast That's a wrap on Season 1.
