Many people today grew up with cellphones in their cribs. They have no idea what information starvation is like. The experience of receiving information you've been waiting for for weeks or months is exhilarating.
Anyway, when you take the library experience versus the experience of pulling up information from a cellphone the improvement is astronomical. From cellphone to voice assistant, the improvement seems very marginal.
Cell phones even represented a distinct advantage over desktops and laptops in that they were always there on your person. Cell phones opened up the possibility to look up information anywhere. With voice assistants it seems the only advantage you gain over cell phones in that you don't have to use your fingers. That doesn't seem very life changing by comparison, unless you don't have fingers, in which case I will admit your life would be vastly improved.
But the downside is that you're connecting a always-on microphone access to mega-corporations who are looking to monetize your existence. For those of us who grew up without the internet or cell phones the trade-off just makes zero sense. We're willing to use cell phones because they open up new worlds of information access. But voice assistants just seems to create more problems than they solve.
