It’s more a matter of how the child develops. We developed by playing ball or climbing trees or building blocks, etc. Our brains developed without being in crisis mode all the time. It was a slower, more patient development. We had to learn patience. We had to learn social skills. Technology can displace that in a negative way.
My 7th and 8th grade year was in a Special Education/Rehabilitation Center. The Rehabilitation being focused on kids with learning and physical issues. I saw kids with everything a kid can have. It was actually a regional {about six county} school with about 500 students that served the Knoxville, TN area. Only a few were ADD ADHD. Polio, MD, CP, Autism, Dyslexia, Open Spine, hearing impairment and visual impairments were the main issues. It got closed down later on I think in the late 1980's due to mainstreaming. Who benefited? The schools they went to got extra funds for doing nothing for the kids. Who suffered? The kids. They lost the help they were getting. Special Education Teachers have a special ability to teach kids with problems most other teachers do not have or do not have time for.
I made it through high school and completed two post high school Voc/Tech courses in different fields. In today's schools I would not have stood a chance.
