I sat on this story for weeks. Felt exploitative.

What changed: I don't want you saying "If I could turn back time, I'd force them to quit."

Check on anyone covering multiple roles.

We celebrate people who pick up everyone's slack. Then we bury them.

Gao Guanghui was 32. Programmer, just promoted to manager. Covering work of 6-7 people. 995.5 schedule: 9am-9pm Mon-Fri, half-day Saturday.
One Saturday he woke up feeling off.

This is the promotion trap: work hard, get promoted, drown under more responsibility with fewer resources. 53% of managers report burnout?higher than ICs.

At EvenUp, I caught myself coding in a hospital waiting room. That's when I knew something broke.

We run on boring open source:
- LangChain/LangGraph
- OpenSearch
- Langfuse

Nothing vendor-locked. Everything swappable. No sales calls. No contracts.

Open source wins because it's boring.

Would you trade speed for support, or are you chasing something else?

[Bob Bui @bobbuitech]

We spend $100k+/mo on AI infrastructure. OpenAI launched Frontier for enterprise. Not interested.

Their pitch: "Managed environment. Built-in governance."

Reality: When you find a better model, you're calling your account rep. Waiting for approval.

Speed dies in bureaucracy.

Last Tuesday: Our ML engineer drops in Slack "New Cohere model is 20% better on our queries."

Switched that afternoon.

Week before: OpenAI endpoint timed out at 11am. Error rate hit 40%.
Rerouted to Anthropic in 8 minutes.

LangChain + LangGraph = just update config and ship.

We spend hours debating GPU vendors and cloud lock-in.

Meanwhile, the actual bottleneck? Zero alternatives.
How deep do you trace your technical dependencies?
RT if this surprised you

[Bob Bui @bobbuitech]

Your AI stack has a 100% monopoly at its base. It's not NVIDIA.

I mapped our entire dependency chain and found ASML at the bottom?100% monopoly on EUV lithography. Every AI chip requires their machines.

[Bob Bui @bobbuitech]

One machine: $400M. Intel bought their entire 2024 production. 30-year moat, 5,000 suppliers, zero competitors.

Any challenger needs 20+ years to replicate the IP.

The first real evidence that the days of LLM Scaling laws are over.

Introducing SCOPE: the world's most efficient Neural Planner. 🔍📊

We tested SCOPE vs Frontier LLMs for planning tasks on TextCraft (text version of Minecraft) and here are the results: ⤵️

- SCOPE Runs 55x faster than GPT 3.5 (3 seconds vs 164 seconds)

- SCOPE is 160,000 smaller than GPT 4o (11M parameters vs 1.8T parameters)

- SCOPE is more accurate on Planning tasks (56%) than frontier LLM models

The age of efficient AI models starts now.

@The_AI_Investor Too fast and furious!
Hardware cycles are outrunning deployment. Most teams will still be optimizing Blackwell software by the time Rubin actually hits the racks.

[Bob Bui @bobbuitech]

@jenzhuscott Sensible though!
Cool demos raise capital and help with marketing but utility builds companies.
Hardware is cheap now, but reliability in unstructured work is still the real bottleneck.

[Bob Bui @bobbuitech]

@jaynitx This is the best filter for the big pivots, but a trap for daily shipping.
You can't treat every minor bug like a life-defining moment or you'll never move fast enough.

[Bob Bui @bobbuitech]

@The_AI_Investor Alpha is just a reward for ignoring the macro noise.
Most people trade the headlines and lose to the index on friction alone.

[Bob Bui @bobbuitech]

@tunguz I bet the HOA rules there are a 400-page PDF of pure edge cases.

[Bob Bui @bobbuitech]

@Ronald_vanLoon @Python_Dv Great list!
Agentic AI lives or dies by tool calling reliability. Without it, you have a chatbot.

[Bob Bui @bobbuitech]

@Arronwei3n Hard to value the ASIC upside if the core business gets squeezed by memory costs.

[Bob Bui @bobbuitech]

@newstart_2024 True! tenacity is the only moat that matters.
Incumbents have more capital, but they can't buy the will to keep going when the odds are zero.

[Bob Bui @bobbuitech]

@tokumin yep, when code is a commodity, the only moat is the data and user context. If a tool does not know me better than the next one, there is nothing stop me from switching.
