Early diagnosis and intervention can reduce cost of lifelong care by 2/3.  Unfortunately cost of intensive early intervention is very high (ranging from $40,000 to $80,000 per year). Therefore, many healthcare insurers, state and local programs are reluctant to pay, making it very difficult for families of autistic children to obtain these essential services. 
The sharp rise in the number of children diagnosed with ASD has strained the limited, labor-intensive behavioral therapy resources, and many children face considerable delays in obtaining these much-needed interventions. 
The high demand for in-person therapeutic autism services combined with recent technological advances have led to a rapid increase in attempts to deliver interventions through digital modalities.
