“My most negative opinion is we don’t have any privacy anymore because everything about us is now recorded someplace and accessible to somebody who has enough intense desire to get it,” said Cooper, who spoke with The Associated Press at in Barcelona, where he was receiving a lifetime award.

Yet the 94-year-old self-described dreamer also marvels at how far cellphone design and capabilities have advanced, and he believes the technology’s best days may still be ahead of it in areas such as education and health care.

“Between the cellphone and medical technology and the Internet, we are going to conquer disease,” he said Monday at .

Cooper, whose invention was inspired by Dick Tracy's radio wristwatch, said he also envisions a future in which cellphones are charged by human bodies.

It’s a long way from where he started.

Cooper made the first public call from a handheld portable telephone on a New York City street on April 3, 1973, using a prototype that his team at Motorola had started designing only five months earlier.

To needle the competition, Cooper used the Dyna-TAC prototype — which weighed 2.5 pounds and was 11 inches long — to call to his rival at Bell Labs, owned by AT&T.

“The only thing that I was worried about: ‘Is this thing going to work?’ And it did,” he said.

The call helped kick-start the cellphone revolution, but looking back on that day Cooper acknowledges, “we had no way of knowing this was the historic moment.”

He spent the better part of the next decade working to bring a commercial version of the device to market, helping to launch the wireless communications industry and, with it, a global revolution in how we communicate, shop and learn about the world.

Still, Cooper said he’s “not crazy” about the shape of modern smartphones, blocks of plastic, metal and glass. He thinks phones will evolve so that they will be “distributed on your body,” perhaps as sensors “measuring your health at all times.”

Batteries could even be replaced by human energy.

“You ingest food, you create energy. Why not have this receiver for your ear embedded under your skin, powered by your body?” he imagined.

While he dreams about what the future might look like, Cooper is attuned to the industry's current challenges, particularly around privacy.

In Europe, where there are rules, about apps and digital ads that track user activity, allowing technology and other companies to build up rich profiles of users.

“It’s going to get resolved, but not easily,” Cooper said. “There are people now that can justify measuring where you are, where you’re making your phone calls, who you’re calling, what you access on the Internet.”

is another area that needs limits, Cooper said. One idea is to have “various internets curated for different audiences.”

Five-year-olds should be able to use the internet to help them learn, but “we don’t want them to have access to pornography and to things that they don’t understand,” he said.

As for his own phone use, Cooper says he checks email and does online searches for information to settle dinner table arguments.

However, “there are many things that I have not yet learned,” he said. “I still don’t know what TikTok is.”
