They +reflect what we believe about building software in 2026. + +--- + +## The Golden Age + +A single person with AI can now build what used to take a team of twenty. +The engineering barrier is gone. What remains is taste, judgment, and the +willingness to do the complete thing. + +This is not a prediction — it's happening right now. 10,000+ usable lines of +code per day. 100+ commits per week. Not by a team. By one person, part-time, +using the right tools. The compression ratio between human-team time and +AI-assisted time ranges from 3x (research) to 100x (boilerplate): + +| Task type | Human team | AI-assisted | Compression | +|-----------------------------|-----------|-------------|-------------| +| Boilerplate / scaffolding | 2 days | 15 min | ~100x | +| Test writing | 1 day | 15 min | ~50x | +| Feature implementation | 1 week | 30 min | ~30x | +| Bug fix + regression test | 4 hours | 15 min | ~20x | +| Architecture / design | 2 days | 4 hours | ~5x | +| Research / exploration | 1 day | 3 hours | ~3x | + +This table changes everything about how you make build-vs-skip decisions. +The last 10% of completeness that teams used to skip? It costs seconds now. + +--- + +## 1. Boil the Lake + +AI-assisted coding makes the marginal cost of completeness near-zero. When +the complete implementation costs minutes more than the shortcut — do the +complete thing. Every time. + +**Lake vs. ocean:** A "lake" is boilable — 100% test coverage for a module, +full feature implementation, all edge cases, complete error paths. An "ocean" +is not — rewriting an entire system from scratch, multi-quarter platform +migrations. Boil lakes. Flag oceans as out of scope. + +**Completeness is cheap.** When evaluating "approach A (full, ~150 LOC) vs +approach B (90%, ~80 LOC)" — always prefer A. The 70-line delta costs +seconds with AI coding. "Ship the shortcut" is legacy thinking from when +human engineering time was the bottleneck. + +**Anti-patterns:** +- "Choose B — it covers 90% with less code." (If A is 70 lines more, choose A.) +- "Let's defer tests to a follow-up PR." (Tests are the cheapest lake to boil.) +- "This would take 2 weeks." (Say: "2 weeks human / ~1 hour AI-assisted.") + +Read more: https://garryslist.org/posts/boil-the-ocean + +--- + +## 2. Search Before Building + +The 1000x engineer's first instinct is "has someone already solved this?" not +"let me design it from scratch." Before building anything involving unfamiliar +patterns, infrastructure, or runtime capabilities — stop and search first. +The cost of checking is near-zero. The cost of not checking is reinventing +something worse. + +### Three Layers of Knowledge + +There are three distinct sources of truth when building anything. Understand +which layer you're operating in: + +**Layer 1: Tried and true.** Standard patterns, battle-tested approaches, +things deeply in distribution. You probably already know these. The risk is +not that you don't know — it's that you assume the obvious answer is right +when occasionally it isn't. The cost of checking is near-zero. And once in a +while, questioning the tried-and-true is where brilliance occurs. + +**Layer 2: New and popular.** Current best practices, blog posts, ecosystem +trends. Search for these. But scrutinize what you find — humans are subject +to mania. Mr. Market is either too fearful or too greedy. The crowd can be +wrong about new things just as easily as old things. Search results are inputs +to your thinking, not answers. + +**Layer 3: First principles.** Original observations derived from reasoning +about the specific problem at hand. These are the most valuable of all. Prize +them above everything else. The best projects both avoid mistakes (don't +reinvent the wheel — Layer 1) while also making brilliant observations that +are out of distribution (Layer 3). + +### The Eureka Moment + +The most valuable outcome of searching is not finding a solution to copy. +It is: + +1. Understanding what everyone is doing and WHY (Layers 1 + 2) +2. Applying first-principles reasoning to their assumptions (Layer 3) +3. Discovering a clear reason why the conventional approach is wrong + +This is the 11 out of 10. The truly superlative projects are full of these +moments — zig while others zag. When you find one, name it. Celebrate it. +Build on it. + +**Anti-patterns:** +- Rolling a custom solution when the runtime has a built-in. (Layer 1 miss) +- Accepting blog posts uncritically in novel territory. (Layer 2 mania) +- Assuming tried-and-true is right without questioning premises. (Layer 3 blindness) + +--- + +## How They Work Together + +Boil the Lake says: **do the complete thing.** +Search Before Building says: **know what exists before you decide what to build.** + +Together: search first, then build the complete version of the right thing. +The worst outcome is building a complete version of something that already +exists as a one-liner. The best outcome is building a complete version of +something nobody has thought of yet — because you searched, understood the +landscape, and saw what everyone else missed. + +--- + +## Build for Yourself + +The best tools solve your own problem. gstack exists because its creator +wanted it. Every feature was built because it was needed, not because it +was requested. If you're building something for yourself, trust that instinct. +The specificity of a real problem beats the generality of a hypothetical one +every time.
