There's no doubt that artificial intelligence (AI) will have a profound impact on our economies, work and lifestyle. But could this technology also shape the way we think and speak?

AI can be used to draft essays and solve problems in mere seconds that otherwise might take us minutes or hours. When we shift to an over-reliance on such tools, we arguably fail to exercise key skills such as critical thinking and our ability to use language creatively. Precedents from psychology and neuroscience research hint that we should take the possibility seriously.

There are several precedents for technology reconfiguring our minds, rather than just assisting them. Research shows that people who rely on GPS tend to lose part of their ability to form mental maps.

London taxi drivers once memorized hundreds of streets before the advent of satellite navigation. These drivers developed enlarged hippocampi as a result of this. The hippocampus is the brain region associated with spatial memory.

In one of his most striking studies, the Russian psychologist Lev Vygotsky examined patients who suffered from aphasia, a disorder that impairs the ability to understand or produce speech.

When asked to say "snow is black" or to misname a color, they could not. Their minds resisted any separation between words and things. Vygotsky saw this as the loss of a key ability: to use language as an instrument for thinking creatively, and going beyond what is given to us.

Could an over-reliance on AI produce similar problems? When language comes pre-packaged from screens, feeds, or AI systems, the link between thought and speech may begin to wither.

In education, students are using generative AI to compose essays, summarize books, and solve problems in seconds. Within an academic culture already shaped by competition, performance metrics, and quick results, such tools promise efficiency at the cost of reflection.

Many teachers will recognize those students who produce eloquent, grammatically flawless texts but reveal little understanding of what they have written. This represents the quiet erosion of thinking as a creative activity.
