Computer Science Didn't Explode. The Job Market Did.

At a job fair, the computer science booth has a line. The civil engineering booth has empty chairs. Online, people say CS is dead. In group chats, students still ask how to transfer into it. Both things are true. They are just about different problems.

When the internet says CS “exploded,” it means the growth is gone. The salary premium has shrunk. Big tech is not expanding. Junior programmers are oversupplied. Thirty-five-year-old anxiety is louder. AI is eating some entry-level coding work. All of that happened.

People transferring into CS are looking at a different math. They are not asking whether CS is great. They are asking whether anything else is better. For many, the answer is no. CS still leaves more exits than most majors.

The whole job market is contracting. CS used to be the exception. Now it is not. But when everything falls, some majors can bend. Others crash. CS can bend.

I. The Explosion Is in Growth and Premium

Ten years ago, CS was a shortcut for ordinary families. A bootcamp graduate who could write CRUD could get an outsourcing job. A CS major who could grind a few algorithm problems could try for big tech. If they caught the mobile internet wave, options and stock could change their class. The story was high pay, comeback, grassroot friendly.

Now? Big tech hires less. Small and mid-sized companies close. Outsourcing cuts rates. Bootcamps mass-produce junior programmers. CS majors compete with each other. Before, there were many jobs and few people. Now there are few jobs and many people. Before, companies fought over people. Now hundreds of resumes fight over one job. Before, writing code was enough. Now degree, projects, internships, algorithms, interview trivia, open source, and competitions all matter.

AI adds pressure. Copilot, Cursor, and large-model tools handle some junior work. A front-end developer used to slice designs and build pages. Now AI generates much of it. A junior back-end developer used to write APIs and tests. Now AI can handle part of that. So the internet says: CS exploded. Do not transfer. Transferring is like joining the losing side in 1949.

Those warnings are not groundless. CS moved from mindless high pay to high competition, strong stratification, and dependence on school, ability, and luck. But other majors?

II. Other Industries Broke First

Look only at the internet, and CS looks finished. Look at the whole job market, and the picture changes. Many industries have been failing longer.

Civil engineering, architecture, and real estate were once hot. Now real estate defaults. Design institutes cut pay. Construction units drift year-round. Civil engineering went from infrastructure pride to grab-your-bucket-and-run.

Biology, chemistry, environment, and materials are called the four great pits. These majors have value. The problem is few industry jobs, low pay, long master's and PhD cycles, and an ugly input-output ratio. Many students finish a master's and find a salary worse than a CS bachelor's.

Finance used to attract top liberal arts and science students. Now brokerages cut pay, funds lay off, and bank tellers are automated. Finance is no longer the million-yuan-a-year finance.

Liberal arts face the same squeeze. Chinese language and literature, law, journalism, and public administration mostly aim at civil service and public institution exams. There are only so many positions. Hundreds compete for one. Corporate clerical, operations, and administrative roles have low thresholds, easy replacement, and low salary ceilings.

When all industries contract, CS contracts too. But CS has a large total number of positions, wide industry distribution, a relatively high salary floor, many transfer interfaces, and many civil service positions. That is enough.

Ordinary people do not choose the best major. They choose the least bad option among limited ones. When every road is hard, a narrower road that still works is a good road.

III. CS Invades Other Industries

CS's most unusual trait is not its own strength. It can enter other industries.

When CS was booming, people said that during any industry transformation, CS has the strongest invasiveness. First came Internet Plus, which redid retail, catering, travel, finance, and education. Then came Mobile Internet Plus, which turned the phone into an external organ. It packed in traffic, payments, social networking, and content. These waves absorbed many CS talents and gave CS majors the full dividend.

Now Internet Plus and Mobile Internet Plus have slowed. AI Plus arrived. Every industry hypes AI: AI plus healthcare, finance, manufacturing, education, law, government. Whether the project lands or not, budgets appear, projects get approved, and teams get built. Those teams still need CS backgrounds. Algorithms, development, data, operations, security, and product roles go to these people.

That is CS's invasiveness. Civil engineering goes to construction sites, design institutes, and real estate. Medicine goes to hospitals and pharma. Law goes to firms, courts, procuratorates, and corporate legal. CS can go to the internet, manufacturing for industrial software, finance for quant risk control, healthcare for medical informatization, government for digital services, car companies for smart cockpits, and energy for dispatch systems. It is like English during the great foreign trade era. Every industry needs a little. Whatever industry you enter, you can connect it to something.

IV. Civil Service Exams Still Favor CS

Many people say they are tired. They do not want to grind tech. They do not want engineering. They want stability inside the system. CS remains one of the friendliest majors for civil service exams, alongside Chinese language and law.

Look at civil servant and public institution job lists. CS majors can apply to many positions. Tax bureaus, customs, public security, statistics, meteorological bureaus, audit offices, cyberspace administration, big data bureaus, government service centers, information centers, and data centers need CS. Even many positions without major restrictions accept CS. State-owned enterprises, banks, power grids, tobacco, and telecom operators have IT positions.

By contrast, many traditional engineering, science, and liberal arts majors can only apply to three-no positions. Competition ratios often reach hundreds to one. CS at least gives you one more track.

The ordinary person's calculation: I may not make big money, but I cannot have no fallback. CS gives a fallback.

V. AI Is a Shock and a Remaining Table with Meat

Everyone says AI will replace programmers. That is half true.

AI will replace some junior coding jobs. It hits work with high repetition, low creativity, and low business understanding. It also creates positions: large-model training, inference optimization, AI application development, data engineering, prompt engineering, AI product, AI security, and AI governance. These roles have higher thresholds, higher pay, and still depend on CS backgrounds.

AI is not a standalone industry. It enables other industries. Every industry wants to redo itself with AI. People who understand both AI and the industry are rare. A CS background plus industry knowledge still beats an industry background alone.

AI cuts low-end positions and raises the ceiling of high-end positions. For people who can move up, it is an opportunity. For people who coast, it is a disaster.

VI. CS Is Not a Shrine or a Safe Box

Saying this is not telling you to charge in blindly. CS has severe problems.

First, oversupply. CS majors, transfer students, cross-discipline exam takers, and bootcamps all squeeze in. If you transfer now, you may graduate at the supply peak. Then the problem is not CS exploding. It is you exploding.

Second, stratification. Top-school CS students with projects, internships, and competitions can still get decent offers. Ordinary-school students who follow videos to type code, with no projects and no internships, may not get interviews. CS no longer means study the major and eat. It means study it well and eat.

Third, AI eats junior positions. Junior programmer used to be the entry stage. Now that stage is compressed. If you cannot rise quickly into business understanding, system design, architecture, algorithms, or industry knowledge, you are easy to replace.

Fourth, age anxiety is real. Internet work is high-intensity, fast, and full of overtime. It demands physical strength and energy. The 35-year-old crisis is not a joke. Many people live it. CS has many transfer paths, but transferring early matters.

CS is not a shrine. It is not a safe box. It is a relatively not-bad choice. It is not a once-and-for-all answer.

VII. When CS Becomes a Pit Major

CS will fall off the altar only when other industries recover and CS alone is dragged to the bottom.

Right now, other industries are bad. CS is bad. But CS is dragged down slower, lighter, and with more fallback options. A starved camel is not bigger than a horse. Everyone collapsed. Some can adapt. Some can only crash-land.

CS becomes a pit when several conditions are met:

First, other industries recover broadly. Pay, positions, and stability improve. CS loses its relative advantage.
Second, CS supply clears. People stop piling into transfers, cross-discipline exams, and bootcamps.
Third, AI dividends no longer depend on many CS backgrounds. Other majors can enter easily.
Fourth, civil service and public institution exams stop favoring CS.
Fifth, CS itself has no new growth point and becomes a traditional industry.

None of these conditions is fully true now. CS is not a pit. It is high competition, strong stratification, and relatively preferred.

VIII. Ending

Online shouts that CS exploded. The shout carries emotion, tail cases, disappointment from people who once had high salaries, and despair from junior programmers facing involution. In reality, people transfer into CS because they are doing survival math. Ordinary families' children make rational choices among limited options.

The market is bad. People still have to work and eat. When everyone is dragged down, you pick the relatively good option. CS is that option. It can grind tech, take civil service exams, transfer careers, combine with industries, and act as an interface in the AI wave.

It is no longer a shrine. It has not become a pit. It is like English during the great foreign trade era, a general tool for every industry, and a fallback for ordinary people. You can say it is no longer glamorous. You cannot say it is useless.

In a study room, a transfer student stares at a Java tutorial. A civil service job list sits beside him. He does not want to change the world. He wants options.
