It's like asking "How long until a bulldozer [1] fully replaces a human construction worker?" A bulldozer is not a full replacement for a human construction worker. However, 1 worker with a bulldozer can do the work of 10 workers with shovels. And 10 workers with bulldozers can build things no amount of workers with shovels can.
[1] I'm using bulldozer as shorthand for all automated construction equipment - front end loaders, backhoes, cranes, etc.
New tech drives job changes. Always has, always will. No guarantee that the changes are good for every individual. And there’s no guarantee that they are good in the aggregate, either.
Never? Google will probably reduce their SWE more and more assuming we get exponentially better at LLMs or something better comes along, but it won't ever be fully replaced.
