Article is missing the obvious....
“Our current era of mobile tech doesn’t measure up to the radical 1990s,” he said, as shown by the fact that productivity gains appear to have stalled for a decade or more.
I'm not sure that's technologys fault. For reasons that remain unclear, whenever the productivity problem is discussed, it gets pinned onto the financial crisis, when its far more likely caused by the Millennials entering the workforce and not being robust or skilled enough to perform.
“Even with the most generous assessment of mis-measurement we cannot explain the slowdown in productivity since the mid-2000s.”
Again, the clue is in the skinny jeans, comedy hair, and excessive sensitivity & emotion.
Anyway, the article misses the point - there will be a 10-15 year lead time for white collar roles to be replaced with AI, AFTER we can produce an AI that can handle the tasks; We're not there yet. Cutting code is only one part of being a developer, the main part, sure, but there's the other stuff such as interpreting vague requirements, knowing what the spec doesn't state, etc etc. The same applies for other roles - accountants and solicitors both attempt to interpret the law in ways their principle finds most beneficial, rather than simply follow rules.
Once we have the tech working properly, there comes the cost of scale issue - spending billions developing the AI will make it initially very expensive to use, meaning its cheaper to stick with fleshy staff. Eventually that cost comes down and role decimation follows, but we're at leats decades away from any threat there.
Boomers and Gen X will be retired, and the Millennials will have to figure out how to respond to it, but that's no different to the role evolution previous generations have adapted to and overcome - 25 years ago many roles that seem ubiquitous today didn't exist and were not readily forseeable.
