Holding the bulky brick cellphone he91裸聊视频檚 credited with inventing 50 years ago, Martin Cooper thinks about the future.

Little did he know when he made the first call on a New York City street from a thick gray prototype that our world 91裸聊视频� and our information 91裸聊视频� would come to be encapsulated on a sleek glass sheath where we search, connect, like and buy.

He91裸聊视频檚 optimistic that future advances in mobile technology can transform human lives but is also worried about and young people.

91裸聊视频淢y most negative opinion is we don91裸聊视频檛 have any privacy anymore because everything about us is now recorded someplace and accessible to somebody who has enough intense desire to get it,91裸聊视频� the 94-year-old told The Associated Press at , the where he was getting a lifetime award this week in Barcelona.

Besides worrying about the erosion of privacy, Cooper also acknowledged the negative side effects that come with , such as internet addiction and making it easy for .

But Cooper, describing himself as a dreamer and an optimist, said he91裸聊视频檚 hopeful that advances in cellphone technology have the potential to revolutionize areas like education and health care.

91裸聊视频淏etween the cellphone and medical technology and the Internet, we are going to conquer disease,91裸聊视频� he said.

It91裸聊视频檚 a long way from where he started.

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

Cooper used the Dyna-TAC phone to famously call his rival at Bell Labs, owned by AT&T. It was, literally, the world91裸聊视频檚 first brick phone, weighing 2.5 pounds and measuring 11 inches. Cooper spent the best part of the next decade working to bring a commercial version of the device to market.

The call helped kick-start the cellphone revolution, but looking back on that moment 50 years later, 91裸聊视频渨e had no way of knowing this was the historic moment,91裸聊视频� Cooper said.

91裸聊视频淭he only thing that I was worried about: 91裸聊视频業s this thing going to work?91裸聊视频� And it did,91裸聊视频� he said Monday.

While blazing a trail for the wireless communications industry, he hoped that cellphone technology was just getting started.

Cooper said he91裸聊视频檚 91裸聊视频渘ot crazy91裸聊视频� about the shape of modern smartphones, blocks of plastic, metal and glass. He thinks phones will evolve so that they will be 91裸聊视频渄istributed on your body,91裸聊视频� perhaps as sensors 91裸聊视频渕easuring your health at all times.91裸聊视频�

Batteries could even be replaced by human energy.

91裸聊视频淭he human body is the charging station, right? You ingest food, you create energy. Why not have this receiver for your ear embedded under your skin, powered by your body?91裸聊视频� he imagined.

Cooper also acknowledged there91裸聊视频檚 a dark side to advances 91裸聊视频� the risk to privacy and to children.

, where there are , and elsewhere are concerned about apps and digital ads that track user activity, allowing tech and digital ad companies to build up rich profiles of users.

91裸聊视频淚t91裸聊视频檚 going to get resolved, but not easily,91裸聊视频� Cooper said. 91裸聊视频淭here are people now that can justify measuring where you are, where you91裸聊视频檙e making your phone calls, who you91裸聊视频檙e calling, what you access on the Internet.91裸聊视频�

is another area that needs limits, Cooper said. One idea is to have 91裸聊视频渧arious internets curated for different audiences.91裸聊视频�

Five-year-olds should be able to use the internet to help them learn, but 91裸聊视频渨e don91裸聊视频檛 want them to have access to pornography and to things that they don91裸聊视频檛 understand,91裸聊视频� he said.

The inspiration for Cooper91裸聊视频檚 cellphone idea was not the personal communicators on Star Trek, but comic strip detective Dick Tracy91裸聊视频檚 radio wristwatch. As for his own phone use, Cooper says he checks email and does online searches for information to settle dinner table arguments.

However, 91裸聊视频渢here are many things that I have not yet learned,91裸聊视频� he said. 91裸聊视频淚 still don91裸聊视频檛 know what TikTok is.91裸聊视频�
