Well I disagree that tech is changing the majority of jobs. I agree that for some professions, some trades; yes, no doubt it is changing the way they work. In what is progressively becoming a service economy, the changes in most jobs are at the periphery.
Your relatively small 'screen time' growing up was probably to some degree more productive than spending every waking hour snapchatting, playing angry birds or on facebook, or any of the extremely simplified software/apps most young people are using in the majority of their technology interaction. The onus to have some even basic degree of understanding of what's under the 'hood' of the flashy colorful gui is vanishing incredibly quickly and I think this is going to be a serious deleterious factor to current children's aptitude for engaging on anything but a surface level with technology into the future.
I can't think of any job that
hasn't been drastically changed by technology - even craftsmen who have been doing the same artisan bollocks for centuries are now hawking their wares on ebay and the like to people all around the world.
The fact that 99% of employers will have their staff's mobile numbers is another drastic change.
Paycheques. Remember them?
We're having this discussion online and most of us are at work. yet how many of us would consider 'doing shit with computers' to be the main description of their job?
As for kids being engaged at only the surface level with programs, it doesn't take long before they are looking for ways to get around the programs limitations. Just ask any teen how to set up a vpn or get around their school's firewall...
