No, though that comes with an asterisk: cultured pearl farming already automated most of the world's pearl supply a century ago. What survives is heritage diving, and its value is precisely that a human went down there.

Our AI replacement risk score — how we score jobs
A working pearl diver's day is physiological before it is romantic. Boat out to a known oyster bed, read the tide and visibility, then repeated breath-hold descents of ten to twenty metres, each lasting a minute or two, prying oysters off the bottom into a net bag while managing equalization, cold and CO2 tolerance. Topside there is sorting, opening shells, grading the rare find, maintaining boats and compressors, and — in Bahrain and the Gulf especially — licensing, quota compliance and the tourism side, where divers now take visitors out and narrate a trade that once ran an entire economy.
Automation ate this industry long ago, just not with robots. Mikimoto's cultured pearl technique made wild pearls commercially irrelevant, and modern pearl farming is a controlled aquaculture operation with grafting, monitored water quality and increasingly automated grading — machine vision sorts pearls by lustre, roundness and surface flaw faster and more consistently than a human eye. Underwater, ROVs and side-scan sonar can map beds, and commercial harvesting of other shellfish uses dredges that no diver could compete with on cost.
So why is the human still there? Because the remaining wild-dive market sells provenance and experience, not molluscs. A Bahraini natural pearl certified as free-dived commands its price from the story and the certification regime around it; a machine-harvested equivalent would destroy the premium it was built to capture. The heritage-diving licence structure exists to keep it that way. Meanwhile the tourism and cultural-preservation strand — UNESCO-listed pearling routes, museum programs, demonstration dives — is a performance job where automating the performer defeats the point. The real risks to this occupation are ecological: bed depletion, warming and salinity, coastal development. Our low score is about robots, not about the future of the beds themselves.
Automatability: our editorial assessment of current and near-term AI capability
Nothing new is coming for the diver this decade — the disruption already happened in 1916 and it was aquaculture, not automation. Through 2040 expect surveying, grading and traceability to be machine-run while the dive itself stays human because human-dived is the selling point. The variable that actually decides this occupation's future is the health of the beds.
Aquaculture did, not machines. Cultured pearl farming from the early twentieth century collapsed the wild pearl trade and with it the great Gulf diving fleets. What remains is a small licensed heritage industry where the human dive is the product. So the honest answer is that the replacement event happened over a century ago and had nothing to do with computers.
Technically plausible — ROVs already work at these depths and grippers can handle shellfish. Commercially it makes no sense. The premium on a naturally dived pearl comes from provenance and tradition, both of which evaporate if a machine did the collecting. You would spend money to destroy the value you were harvesting.
As a sole occupation, rarely. Most people in it now combine licensed seasonal diving with tourism, teaching, boat operation or other commercial diving work. In Bahrain the trade is deliberately preserved and regulated as cultural heritage, which stabilizes it but also caps its size. Treat it as one strand of a diving and heritage-based livelihood.
The sea. Bed depletion, dredging for coastal development, warming water and salinity shifts do more damage to pearling than any technology. Add the physical toll — decades of breath-hold diving is hard on ears, lungs and joints. Conservation policy and diver health, not automation, are what determine whether anyone is diving in 2050.
