My 15 year old son has a CPAP and it changed his life. He is no longer tired after a long nights rest.
I mean, just because the internet relies on computers doesn't mean it's not more significant imo. A PC on its own was cool and definitely transformative, but not like the internet has been on the last 25 years or so.
It's the combination of the two that has been transformative. If you had the internet, but limited to large institutions on expensive shared machines, it wouldn't have been particularly cool or transformative of everyday live. Cheap, widely accessible computing resources have transformed our lives more, I'd argue; widely available computing resources with pre-internet comms technologies would still have a major impact on our lives.
He's lucky he got diagnosed at an early age. For me the condition went on undetected for years. I knew something was wrong though, it's hard to diagnose sleep apnea
