What are the key takeaways from this The Changelog episode?

Key insights include: **GPT-5.4 for Agent Workflows:** OpenAI's GPT-5.4 is specifically noted by Augment Code as the first model built for agentic coding — it plans, delegates, and follows through without losing context mid-task. Developers using coding agents should test it immediately.; **Biological Computing — CL1 Plays Doom:** Cortical Labs' CL1 device, which uses living human brain cells, now runs Doom as demonstrated on video. This marks a tangible milestone in wetware computing, moving from theoretical research into demonstrable, functional software execution.; **AI Dependency Security Gap:** AI coding agents recommend libraries based on training data with knowledge cutoffs. Sonatype's Guide tool at guide.sonatype.com lets developers search any dependency to surface CVEs disclosed after a model's training cutoff — no account required to use.
