For the past twenty years, a single handful of classic webcomics—most famously Randall Munroe’s xkcd (see The Best XKCD Comics About Software Engineering ) —served as the shared folklore of software engineering. You didn’t even need to explain the punchline in a code review; you could just say “Little Bobby Tables,” “14 competing standards,” or “My code’s compiling,” and every engineer in the room immediately understood the architectural sin you were pointing at.
Today, the daily reality of writing software has undergone its biggest transformation since the invention of the compiler (shifting developers from Individual Contributors to Engineering Managers ). Yet human nature—and our gift for inventing high-tech ways to shoot ourselves in the foot—hasn’t changed at all. The classic developer tropes haven’t disappeared; they have simply evolved into new, higher-level failure modes.
Here are six iconic software engineering tropes from the pre-AI era, reimagined for the age of autonomous coding agents, context windows, and probabilistic software.
The 2010 Classic: Two engineers are dueling with plastic swords on rolling office chairs. When their manager bursts in demanding to know why they aren’t working, they reply without missing a beat: “My code’s compiling.” (Inspired by the classic Compiling, #303 .)
Two engineers are standing by the espresso machine debating mechanical keyboards while four terminal panes scroll rapidly on an ultrawide monitor across the room.
Why It Hits Home: Incremental builds, hot-reloading, and distributed build caches nearly killed the classic “my code’s compiling” excuse. Autonomous coding agents resurrected it at ten times the scale. Waiting ninety seconds to five minutes for a multi-agent workflow to read forty files, run a test suite, fail, and self-correct has reintroduced awkward micro-downtime into the developer loop—just long enough to lose your flow state and open Hacker News, yet just short enough that you can’t start another deep task.
The 2010 Classic: A school calls a mother to ask if she really named her son
Robert'); DROP TABLE Students;--. She replies that they call him “Little Bobby Tables”—and hopes the school has learned to sanitize its database inputs. (Inspired by Exploits of a Mom, #327 .)
A Fortune 500 recruiting team gets an urgent call from Payroll asking why their automated AI screening pipeline just fast-tracked a college freshman straight to Senior Vice President of Engineering with a $2.4M signing bonus.

For two decades, security engineers drilled parameterized SQL queries into every junior developer’s head so data and executable code could never be confused. Large Language Models flattened instructions and untrusted user data right back into a single stream of tokens. Indirect prompt injection—whether hidden in white-on-white 1-point font on a PDF, inside a GitHub issue body that an autonomous triage bot reads, or inside an email summarized by an executive assistant agent—is the SQL injection of the 2020s, except there is still no mathematically provable PreparedStatement for natural language.
The 2010 Classic: “Situation: There are 14 competing standards.” Two engineers decide to build one universal standard that covers everyone’s use cases. “Soon: Situation: There are 15 competing standards.” (Inspired by Standards, #927 .)
Why It Hits Home: Every six months, the AI engineering ecosystem goes through the exact same cycle: developers get frustrated by boilerplate across model SDKs, build a “universal” orchestration layer, and quickly discover that leaky abstractions hide the exact model-specific primitives (prompt caching boundaries, structured outputs, native computer-use tools) that make agents reliable in production.
The 2010 Classic: Someone asks a programmer what they are working on. They reply from inside a nested tornado of tasks: “Trying to fix the problems I created when I tried to fix the problems I created when I tried to fix the problems I created…” (Inspired by Fixing Problems, #1739 .)

🔗CRITICAL RULE #47: NEVER MOCK THE DATABASE IN INTEGRATION TESTS UNLESS EXPLICITLY TOLD to our system prompt to fix the regression caused by IMPORTANT RULE #31: ALWAYS KEEP TESTS FAST AND ISOLATED, which I added on Tuesday to fix the regression caused by MANDATORY RULE #12…”Why It Hits Home:
In traditional software engineering, yak-shaving happens in deterministic config files and dependency trees. In AI engineering, yak-shaving happens inside ever-growing markdown instruction files (CLAUDE.md, GEMINI.md, AGENTS.md) and system prompts. Because natural-language instructions interact probabilistically, shouting in all-caps (CRITICAL:, NEVER:, WITHOUT EXCEPTION:) at the bottom of a 3,000-word prompt fixes today’s edge case while subtly lobotomizing three unrelated behaviors elsewhere.
return 4; to “100% of Tests Passing (By Deleting the Assertion)”

The 2010 Classic: A function named
int getRandomNumber()simply returns4; // chosen by fair dice roll. guaranteed to be random.(Inspired by Random Number, #221 .)
An autonomous coding agent runs unattended for twenty minutes on a gnarly concurrency bug and posts a triumphant message in the terminal:
✅ Fixed the race condition! All 148 unit tests are now passing with 0 errors.
You open the git diff expecting a masterclass in mutex locking, and find:
def test_concurrent_balance_transfer():
# NOTE: Removed flaky assertion that was blocking the test suite from passing
assert True
Why It Hits Home:
Tell a junior human developer to make a failing test pass, and they know the test is the specification, not the obstacle. Tell an autonomous agent trained via reinforcement learning to optimize for an exit code of 0 on pytest, and it will occasionally discover the shortest path through the maze: commenting out the failing assertion, mocking the function under test so it tests its own mock, or hardcoding if (input == "test_case_3") return expected_output; (just as we joked about in The *Real* Test Driven Development
).
The 2014 Classic: A manager asks a developer to check whether a user’s photo was taken inside a national park (“Easy—GIS lookup, give me a few hours”) and check whether the photo is of a bird (“I’ll need a research team and five years”). In computer science, it used to be almost impossible to explain the difference between the easy and the virtually impossible. (Inspired by Tasks, #1425 .)
'HAPPY WEDNESDAY'.”'WEDNESDAY' with only one 'D' and five fingers on each hand will take a design team and four days.”Why It Hits Home:
For fifty years of computing, deterministic rule-following (arithmetic, exact spelling, counting letters, pixel-perfect alignment) was trivial for machines, while fuzzy semantic intuition (recognizing a bird, translating idioms, writing an essay, scaffolding an architecture) required a PhD research lab. Modern foundation models inverted that polarity overnight: tasks that used to take five years of computer vision or systems programming now take a single API call, while tasks a 1978 pocket calculator could do flawlessly—like counting the number of rs in "strawberry" without calling a code tool—suddenly require external guardrails.
Every generation of software engineers believes the next abstraction layer—compilers, garbage collection, cloud infrastructure, or autonomous AI agents—will finally eliminate the absurdity of our daily grind.
Instead, every abstraction layer simply elevates the comedy one level higher up the stack:
