Surely significantly more than 100x. I'd hypothesize 10,000x at minimum from 15 years ago, at least if you measure total bits. Not sure how I could confirm that conjecture though.
In fact it could be less than 1x in many cases. People that would have blogged about their Croatia trip might now instead just have a 10 word tweet, an instagram story (of similar low quality and probably not publicly indexable), or a youtube video (so non text content)
