Podcast: Semi Doped
Published On: Fri Mar 13 2026
Description: Austin recaps moderating an agentic AI panel at Synopsys Converge, then gives an in-depth technical breakdown of Meta's MTIA custom silicon. Why they're building it, how chiplets let them ship a new chip every 6 months, and how the roadmap is shifting toward gen AI inference. Vik digs into Applied Optoelectronics (AAOI), the vertically integrated Texas laser shop whose stock went from $1.48 to $100+, and whether history is about to rhyme.                     Austin Lyons: https://www.chipstrat.comVik Sekar: https://www.viksnewsletter.com/                                                                                                                                  Topics covered:• Agentic AI in chip design — how it changes roles for junior and senior engineers• Optical circuit switching and what it means for Arista's business model• Meta's ad-serving pipeline: Andromeda, Lattice, and the GEM foundation model• Why custom silicon (MTIA) makes sense at Meta's scale• MTIA chiplet strategy — 4 generations in 2 years• AAOI's vertical integration, Amazon's $4B warrant deal, and the 2017 parallelChapters:0:00 Intro1:26 Synopsys Converge — Agentic AI Panel9:44 Vik's Article: Optical Circuit Switching & Arista14:43 Meta MTIA — A New Chip Every 6 Months21:32 Why Custom Silicon Makes Sense for Meta27:22 MTIA Chiplet Strategy & Roadmap33:56 Gen AI Fits Meta's Business Model36:31 How Meta Ships Chips So Fast40:30 Applied Optoelectronics (AAOI) Deep Dive45:02 Amazon's $4B Warrant Deal48:54 Can AAOI's Lasers Compete with Lumentum?53:16 AAOI's Aggressive Capacity Buildout55:35 History Rhymes: AAOI's 2017 Boom & Bust1:00:55 Wrap-Up#semiconductors #chips #tech #meta #MTIA #AAOI #optics #inference #AI
