#142 Why LLMs Need Their Own Programming Language: From Assembly to AI with Vaibhav Gupta // Co-founder @ BAML

From HoloLens assembly to AI: Vaibhav Gupta on why LLMs need their own language, and how BAML makes them type-safe and shippable at agent speed.
BROUGHT TO YOU BY: Blocks (blocks.cloud/alphalist?utm_source=alphalist&am…)

A decade building computer vision and writing assembly at Microsoft (HoloLens), Google, and D.E. Shaw, then a from-scratch bet on a programming language built for LLMs. Vaibhav Gupta joins Tobi to explain why probabilistic compute needs its own tooling, what "shipping at agent speed" actually requires, and why the world's appetite for software is mathematically infinite.

Chapters:
00:00:00 — Intro
00:01:00 — From HoloLens to D.E. Shaw: a decade in computer vision and assembly
00:02:00 — Starting from scratch, and the YC pivot ("500K to not build a Slack competitor")
00:04:00 — Falling in love with coding — and bricking a few machines along the way
00:06:00 — His first AI moment: the GPT-3.5 wake-up call
00:09:00 — Code as a means to an end — why 90% of the job is plumbing
00:11:00 — Why he decided to build a language: first principles and BAML
00:13:00 — LLMs as a new compute primitive
00:15:00 — What BAML actually is — embedded, type-safe, callable from any language
00:17:00 — The business model and the "data trench"
00:19:00 — When AI ships code you didn't ask for — and why CI/CD breaks in an agent loop
00:22:00 — Live demo: function versioning and locking the codebase
00:24:00 — Why no one else competes here — Protobuf, Thrift, and Google's playbook
00:29:00 — Getting started: the BAML "hello world" (live coding)
00:32:00 — Everything is a function — type safety that runs in Rust
00:36:00 — Shipping at agent speed = trust plus granular control
00:38:00 — Visualizing code instead of reading it
00:44:00 — Where to start with BAML (docs.boundaryml.com → Agents MD)
00:45:00 — The mathematically infinite appetite for software
00:47:00 — Why we'll have 10x more builders — and why "English isn't a programming language"
00:51:00 — The future of SaaS: PaaS, harnesses, and customer-defined models
00:56:00 — Will design matter more in an agent world?
00:59:00 — The "time travel" decorator: advice to his 2017 self
01:04:00 — Outro

Quotes:
00:13:00 — "BAML's a new thing that exists because we have a new compute primitive in the form of LLMs." (verbatim)
00:10:00 — "90% of software engineering — well, in most jobs, 100% of software engineering is plumbing… And AI just takes that 90%, just makes it go away."
00:19:00 — "We can now generate code at machine speed… But we still cannot ship code at machine speed."
00:49:00 — "English can't go down to assembly… And the minute you add that to English, what have you done? You've built a new programming language."
00:45:00 — "I don't think we've yet found a company that hasn't found that I can make more money if I write more code."
