I think parent comment meant that progress has accelerated to such a degree that the same amount of innovation will have happened between now and 2029 as happened between 2003 and now.
I disagree with the parent comment.
I don't think they appreciate the scope of change over the last 20 years. From mobile, tablet and headset interfaces, to social media, to infrastructure (ADSL never mind fibre), WiFi, cell tech. Voice assistants, chatgpt, I could go on.
Crumbs, the Web didn't even have ajax back then.
We're not even close to duplicating that scale of change over the next 5 years.
First mover disadvantage.
By then everyone else will have been using it for a while.
