Exactly my point.. And all the industry experts who they must have consulted in to write the laws are coincidently invested in personal data harvesting. Who could have foreseen this happening.
The value rarely shows up where you expected it to.
I kept a rough log of my sleep and mood for about a year with no specific goal. Mostly forgot about it. Then I had a weirdly bad few months and went back to look — turns out there was a pretty clear pattern I would've never noticed in the moment.
Maybe the framing of "was it worth it" is the wrong question. It's less like an investment with a return and more like keeping receipts. Useless 99% of the time, then suddenly you really need one.
