95% of Smartphone use is Instagram, Facebook, WhatsApp, Snapchat, TikToc, etc., Those are novices. They aren't computer professionals. They are narcissistic seeking image influencers selling out to brand other 3rd party junk on these visual feeds.
Their not office professionals working with Databases, large matrix spreadsheets used for real-time data collection, producing technical publications for companies from legal professionals, software manuals, etc.
They are consumers==Novices.
They're not in applied science fields of engineering, chemistry, physics, etc., using their smartphones with their jobs. They are consumption based time wasting portable handheld systems to keep you tethered to Current Events.
