Or horrific if not used correctly. Before I 'retired' I owned an antique mall. A dealer had a rotary dial phone in his booth and when parents brought their children in, none of them understood why a phone was too large to carry in a pocket and had to be dialed one number at a time and wait until the dial returned to its original position to dial the next number. Or the purpose of having to lift the receiver and get a "dial tone".
When I was a teenager, it was a great advancement when "long" cords became available- we could use the phone from almost any adjacent room in the house- amazing!
And I doubt many children know how to read a paper map or take a math course without the use of a calculator- conveniently available on their phone.
Need an essay? Then no need to learn to write properly- Chat will do the work for you.
Much good can come with this innovative technology but unless children are first taught the manual way things work- basic math and writing skills -they'll be lost in acquired ignorance. And I don't want to see us raising a generation of inept morons, with only a few people who understand how things work...
