AI can help you finish some work faster, but faster output is not the same as stronger skill—or weaker skill. The evidence so far shows task-specific productivity gains and changes in the kind of effort people do. It does not establish that regular AI use inevitably erodes independent ability. A sensible boundary is to let AI accelerate the work while keeping ownership of the question, the quality standard, and the final decision.
What the evidence says about getting faster
The clearest workplace result comes from a study of 5,179 customer-support agents. When agents had access to a generative-AI assistant, they resolved 14% more issues per hour on average. The increase was concentrated among novice and lower-skilled workers; experienced and highly skilled workers saw minimal effects. That is a meaningful result for that setting, not a forecast for every job or every AI tool. The study appeared as a 2023 working paper and was published in journal form in 2025. NBER, “Generative AI at Work”.

A 2024 Microsoft Research synthesis likewise cautions against treating productivity as universal. Effects vary with role, function, organization, adoption, and how people use the tool. A task that involves drafting or handling routine requests may respond differently from one that depends on expert judgment, accountability, or deep familiarity with a complex case. Microsoft Research’s overview.

So the useful question is not simply whether AI makes people faster. It is: faster at which task, for whom, and with what effect on accuracy and quality?

Less effort on a task does not mean no thinking
AI can reduce the effort needed to produce a first draft or complete a bounded task, while shifting effort into deciding whether AI is appropriate, breaking work into pieces, writing instructions, checking the answer, and choosing how much to trust it. The work changes shape; it does not necessarily disappear.
In a small Microsoft Research study, 40 employee volunteers prepared a sales report with or without Copilot. Those using Copilot reported lower perceived mental demand: 30 out of 100, compared with 55 out of 100 for the control group. Researchers found no average difference in a subsequent Stroop score. Those results describe one short, specific task and a small group; they do not demonstrate that AI has no long-term effect on cognition or skill. Microsoft Research technical report, July 2024.
The same report describes the metacognitive work involved in using AI well: staying aware of the goal, decomposing a task, judging confidence in an answer, and adapting a workflow when the result is weak. It discusses design ideas such as explainability, self-evaluation, co-auditing, and support for task decomposition. These are useful principles, not proven personal techniques for preventing skill loss.

Short-run task performance and lasting independent skill are different outcomes. A person can complete today’s assignment more efficiently without the available studies establishing whether that person will retain the underlying ability after months or years of using AI. Nor does one short-term result settle how that question varies across occupations and tasks.
A 2026 NBER randomized online experiment examined follow-up performance after AI was removed and reported no worse performance than controls in that experiment. That is evidence about the experiment’s particular task and online sample, not a general estimate of long-term skill retention across jobs. NBER, “Does Generative AI Narrow Education-Based Productivity Gaps? Evidence from a Randomized Experiment”.
The honest answer to “Will AI make me worse at my job?” is therefore conditional. Current findings support the possibility of better performance on certain tasks, especially for some less-experienced workers. They do not prove either inevitable deskilling or durable learning from AI-assisted work.

Use AI differently depending on whether the priority is immediate completion or building a skill. For routine work, it may be reasonable to delegate more of the first pass. When the task is one you need to learn or must be able to perform independently, keep more of the reasoning in your own hands.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errors- Set the goal and standard yourself. Before asking for help, define what a good result must accomplish and what errors would matter.
- Choose the AI’s role deliberately. It can generate a starting point, assist with a step you have already planned, or evaluate work you produced. These roles preserve different amounts of independent practice.
- Check the result against the task, not its confidence or polish. Verify facts, reasoning, completeness, and fit for the audience. Correct errors rather than accepting a fluent answer by default.
- Keep a baseline on meaningful work. Compare an unaided attempt with an AI-assisted one for time, accuracy, and quality—not elapsed time alone. Treat this as a personal check, not a validated test of future skill.
- Practice unaided when the ability itself matters. If you need to diagnose, write, calculate, or decide without help in another setting, make room for occasional practice without AI.
These are cautious working habits drawn from the evidence on changed task demands and the need to evaluate outputs. They are not experimentally established guarantees against skill loss.
Why the distinction matters as AI use spreads
In survey data collected in late 2024, nearly 40% of U.S. adults aged 18–64 reported using generative AI. Among employed respondents, 23% had used it for work at least once in the prior week and 9% used it every work day. These figures describe late 2024, not current 2026 prevalence. Bick, Blandin, and Deming, NBER Working Paper 32966.
As use becomes routine, it is easy to count time saved and harder to notice which parts of a job a person is no longer practicing. That makes it worth tracking both sides: whether AI improves the result now, and whether you can still explain, assess, or reproduce the important parts yourself when needed.
