revenge of the expert systems

ai agents and the myth of the generalist

silicon valley's greatest hits democratize luxury. but not in the way most people think.

uber didn't just bring private drivers to the masses. more importantly, its rating system and data-driven dispatch meant you got the best drivers consistently, not just whoever happened to be at the front of the taxi line.

airbnb didn't just open up vacation homes. it connected travelers with local hosts who knew every hidden restaurant, every quiet beach, every neighborhood secret.

spotify didn't just give us unlimited music. it built recommendation engines that could surface obscure artists and predict your taste better than record store clerks who'd known you for years.

the real luxury being democratized isn't just the surface-level perks, it's expertise.

silicon valley's playbook is clear: find deep expertise, distribute it widely. yet so far AI companies are selling a different dream - promising digital butlers that do everything, and master nothing.

chatgpt will manage your entire life, they say. anthropic's claude will handle all your affairs (business and otherwise). google's gemini stands lonely and ready to serve.

but we've seen this movie before - the dream of the digital generalist that can do it all.

the digital graveyard is full of failed universal assistants. siri collects dust on millions of iphones. google's assistant withers into android wallpaper. alexa masters timers and weather reports, her potential echoing through empty rooms.

tech giants spent a decade chasing the perfect servant and all we got were glorified alarm clocks.

–-

we didn't fail at building universal assistants just because the technology wasn't good enough. we failed because the goal itself doesn't make sense.

nature never builds generalists. four billion years of evolution and not a single species that does everything well. even humans, supposedly the ultimate generalists, succeed through collaboration and extreme specialization.

true utility isn't having one person do everything poorly. it's having specialists who excel in their domains - the sommelier who knows every wine, the tailor who cuts the perfect suit, the chef who masters one specific cuisine obsessively.

a truly useful digital assistant won't do everything themselves. they will be experts at execution - knowing who to call, what to delegate, and when to step back.

this isn't a new insight. in AI's first spring, researchers found themselves drawn to expert systems - programs built to match human specialists in narrow domains.

they recognized something fundamental: domains are naturally bounded, expertise naturally focused.

the technology wasn't ready yet. without the ability to learn from data or understand context, these systems could only follow rigid rules. maintaining their knowledge bases was a nightmare. updating them was nearly impossible.

the dream was right, but the tools were decades too early. so we shelved expert systems, filed them away as a failed experiment.

but now everything they needed has arrived in the form of LLMs.

yet even these models tell us something profound about specialization. peek under the hood of a language model and you'll find not one giant network, but countless specialized sub-networks, each handling different aspects of language and knowledge. some recognize patterns, others generate responses, others check for consistency.

it's experts all the way down.

yet instead of embracing this natural architecture, we're chasing universal assistants. it's as if we've forgotten why specialization evolved in the first place - not as a temporary limitation to overcome, but as the natural shape of intelligence itself.

intelligence specializes, then specializes again. how far down this recursion goes - what fundamental units of thought lie at the bottom - is a mystery for another time.

we are living proof in eight billion forms, each mastering our own corner of the world. no one person handles our taxes, fixes our teeth, and drives us to the airport. this division of labor isn't a bug - it's the feature that built civilization.

even our brains fragment expertise - different regions for vision, speech, movement, each further subdivided into specialized neural circuits. consciousness itself might just be the ultimate delegation system, routing tasks to their perfect processors.

nature doesn't build swiss army knives. it builds eagles with perfect eyes, sharks with perfect teeth, spiders with perfect silk. each one unremarkable except for their singular excellence.

now we can finally build AI the way nature intended. language models don't just process information - they can inhabit domains completely. legal agents that breathe in case law and exhale precise contracts. medical agents that absorb centuries of research and diagnose with crystalline clarity. trading agents that parse market patterns with mathematical precision.

like a surgical team in perfect sync, the real magic unfolds in the handoffs. your health agent monitors vitals while your insurance agent optimizes coverage. your finance agent rebalances portfolios while your tax agent hunts for deductions. each excellent, each essential, none trying to do it all.

and of course, even the LLMs themselves are not monoliths but orchestras - in basic terms, the mixture of experts approach favored by sota models ensures that different parts of the network work in harmony, each handling their slice of the task. humans become conductors, directing not just the agents, but the specialists within specialists.

the future isn't one assistant trying to be everything. it's many assistants, each one perfect in its domain, each one content with its boundaries. a relay race where humans hold the baton, and each expert - down to the smallest neural circuit - runs their perfect stretch at impossible speed.

--

we built machines in our image, but forgot one of our oldest lessons: mastery means choosing what not to master. those early AI pioneers saw it clearly - their expert systems weren't just prototypes, they were prophecies.

our digital future will emerge as nature intended - an ecosystem of specialized minds, each one precisely tuned to its purpose, none attempting to be everything.

generality was always a mirage. the future belongs to the specialists.
