I don't remember believing in any tech utopia for a very long time. On the other hand I regularly see people who still believe we are a few years away from AGI creating one for us. So while it's over for the author it's not so for others.

Personally I can name both areas where tech improved my life beyond expectations (not having to live near work for one) as well as huge disappointments (such as people willingly choosing to believe lies en masse despite truth becoming easily accessible).
