the late 90s was a period where 'agents" were all the rage in popular tech media and in the lexicon of large-scale software architectures.
in the military this was reflected in the idea of various elements able to handle telemitry be able to exchange information securely (e.g., one helicopter on one side of a mountain range could echo what its radar is seeing to another chopper on the other side of that range. the idea of 'agents' was to exchange that information without interactive efforts by either pilot.
in the civilian world this was reflected by the whole "and the company that will bring that to you? AT&T" ad campaign. This idea that the agent will handle scheduling your medical appointments, business appointments, do your flight and apartment bookings when you're planning a vacation. That it could just do it all on your behalf.
Now back then, the issue was APIs. How can we agree on the interfaces such an agent would need. This led to web services, and IBM so over-engineering the code required to do it (code that IBM would nicely provide for you at a cost), that...nobody dared actually go into that space deep enough to fulfill the promises. IBMs hurting over the decades since is partially from this self-inflicted wound of getting into the standards body and trying to corrupt the standards into something so complicated that only IBM could save you from them. The end result?
When was the last time /. actually had a post about web-services?
Been a while, hasn't it? The early 2000s were all about XML and WSDL and all that...and NOTHING of importance (commercially) has come of it. The complexity killed the drive to actually do something.
Now, it is entirely possible for new systems to do that, whether by AI or by basic web-scraping tech...but we're at a new impasse: nobody trusts the corporations that can afford to do it. I mean, yeah, lots of us are on google or amazon or apple or several...but we don't trust them with EVERYTHING. and we don't trust them to just act on our behalf. They can plan things and we can eventually approve (and they can only plan within the info they have, and there's no cross-info available, so google doesn't know my delta info, and apple doesn't know my marriott info, and google and apple sure as bleep aren't talking to each other right now), that the promise of those agents of the 90s could never be achieved.
We all want that Star Trek future where we just go "computer, book a holiday in San Louis Obispo from May 12th through the 15th. Flights, resort, and car." and have it happen, complete with our preferred airline, hotel chain, and rental company...but we don't trust any corporation like Google to actually have access to all that.
So this is the alternative: the AI operates on your browser using info that's only here on your client, and instead of data-accurate web-services, it uses web-scraping to try to handle it all.
but that still leaves you as a person giving up your trust.
