Coding Chats Episode 79 - Richmond Alake, Director of AI Developer Experience at Oracle, joins John to discuss agent memory — how AI agents store, retrieve, and adapt to information. He argues that developers building memory on flat files are naively reinventing the database, and that once you factor in concurrency, security, and scalability, a proper database is inevitable. The conversation covers the full memory stack and how Oracle's AI database keeps embeddings and data together without shipping sensitive information to external providers.
The pair also explore why memory is the most universally relatable concept in AI, the history of how neuroscience shaped LLMs, and the problem of Catastrophic Forgetting that still haunts models today. A sharp AGI debate lands on a sobering point: an LLM is just a function — tokens in, tokens out — and most AI engineers are unknowingly rediscovering solutions that database engineers spent decades building.

Takeaways:
File systems are fine for prototyping, but the moment you hit production scale you're just slowly reinventing the database.

Agent memory isn't a new concept — it's data management, and database engineers have been solving it for decades.
Memory is the single most relatable entry point for explaining AI to anyone, technical or not.
Catastrophic Forgetting isn't a solved problem — it plagued RNNs and still quietly haunts LLMs today.
An LLM is ultimately just a function: tokens in, tokens out — which should temper any claims about sentience or AGI.
The definition of AGI keeps shifting to match whatever AI can't do yet, making the whole debate almost meaningless.
Most AI engineers have less than ten years of experience and are unknowingly rediscovering solutions that search and database engineers spent decades building.
"Vector search is all you need" is one of the most dangerous oversimplifications in AI engineering right now.
Memory engineering — the crossover between data engineering, search optimisation, and agent design — is an emerging discipline that doesn't have a name yet but absolutely should.
The real moat in AI products isn't the LLM itself, it's everything built around it — the harness, the memory, the retrieval pipeline.
