AI May Take Over Most Jobs — Yet These Jobs AI Can’t Replace Are on the Rise

Sep 10

Remember the movie Her? Back in 2013, audiences watched Joaquin Phoenix fall in love with an operating system — a voice so smart, so human-like, it could replace real human connection. At the time, it felt like pure science fiction. Something you’d leave the theater thinking, that’s fascinating, but it’ll never happen in my lifetime.

Fast forward to today, and suddenly it doesn’t feel so far-fetched. AI is writing code, answering customer questions, and even helping companies make big decisions. It hasn’t reached the level of Her, but it’s close enough that many people are asking: is AI taking over jobs — and which jobs are the ones AI can’t replace?

The truth is, while AI will automate certain roles, its growth is driving a massive surge in demand for other careers — skilled, hands-on jobs that keep AI running in the real world.

Find work that makes you feel good

Electricians

Every new AI data center is like a small city when it comes to electricity. Transformers, substations, backup generators, and miles of heavy wiring are all part of the build, and none of it happens without electricians. Their work goes far beyond basic wiring — it’s about ensuring stable, high-voltage systems that can handle the enormous loads AI demands. As companies race to expand, electricians with experience in commercial and industrial systems will be busier than ever. And with apprenticeships leading to steady, well-paid careers, it’s one of the clearest examples of a future-proof trade.

Plumbers and HVAC Technicians

If electricity keeps AI alive, cooling keeps it from burning out. Servers generate intense heat, and without constant cooling, entire data centers could fail in minutes. That’s why plumbers and HVAC technicians are stepping into the spotlight. Plumbers are installing advanced liquid-cooling systems that circulate chilled water around racks of servers, while HVAC specialists manage massive chillers and cooling towers to keep temperatures under control. This isn’t about fixing leaky pipes or home air conditioners — it’s about building and maintaining the critical systems that allow AI to function. As hardware gets more powerful, these jobs will only become more essential.

Power Engineers and Grid Specialists

AI’s growth doesn’t just affect tech companies — it’s reshaping the entire power grid. Data centers consume as much energy as mid-sized cities, and utilities are scrambling to keep up. That’s where power engineers and grid specialists come in. They’re the ones designing smarter grids, planning new substations, and integrating renewable energy to make sure the lights — and servers — stay on. It’s a role that combines technical expertise with big-picture problem-solving, and it’s only going to grow in importance as AI expands. For anyone with an engineering background, this field offers both stability and the chance to work on challenges that matter to the entire economy.

Spillover Jobs: The Ripple Effect

AI infrastructure doesn’t rise from the ground without help from a whole ecosystem of workers. Construction crews pour the concrete and raise the steel. Lineworkers connect high-voltage transmission lines to carry the extra load. Mechanical technicians keep pumps, compressors, and backup generators running smoothly. Even security and facilities teams expand, because data centers require 24/7 protection and support.

Each facility is a reminder that AI may live in the “cloud,” but the cloud has a very real workforce on the ground — and those jobs will thrive as more centers come online.

Not Just a Temporary Spike

Some people assume that once AI data centers are built, the demand for these jobs drops off. But that overlooks a critical truth: data centers aren’t static buildings, they’re living systems.

Electricians are needed long after the first wires are laid, because power loads keep growing and systems must be upgraded. Plumbers and HVAC specialists don’t just install cooling systems — they maintain them, repair them when they fail, and adapt them as servers get hotter and denser. Power engineers keep working as utilities expand capacity and integrate renewables to handle AI’s massive appetite for electricity. And lineworkers, mechanical technicians, and construction teams return again and again for expansions, retrofits, and grid upgrades.

AI infrastructure is never “finished.” Servers are replaced every few years, energy needs keep rising, and companies are racing to build not just one facility but dozens across the globe. That means these jobs don’t vanish after the initial boom — they shift into long-term cycles of maintenance, upgrades, and new builds.

A Different Kind of Future-Proof Career

So yes, AI will replace some tasks. But it’s also fueling demand for skilled trades and technical roles that can’t be automated — jobs that literally make AI possible. Electricians, plumbers, HVAC specialists, engineers, construction crews, lineworkers: these careers aren’t going away. They’re becoming more valuable.

If you’re thinking about your career path, here’s the good news: the future of work isn’t just about competing with AI. It’s about building the industries that AI depends on. And those industries will always need people — skilled, essential, and in demand.
