Is the Age of the Expert Over? | How AI Made the Generalist Valuable

For 250 years the answer was to split work finer. Why is it being glued back together now — and what does that mean for juniors and seniors? Designers are becoming product designers, developers product engineers, and whole consulting teams are collapsing into one role: the forward deployed engineer. For 250 years the rule was to split work finer — so why is it being glued back together? We follow Adam Smith's pin factory, Fred Brooks's lines of communication and ecology's generalist species, then ask what it means now that junior hiring is shrinking — for juniors, for seniors and for the people who hire. Disciplines in this episode: Economics · Software engineering & organizations · Ecology · Labor economics · Epistemology 0:00 PROLOGUE 1:04 Past: why specialization won 2:13 Past: the cost of splitting 3:32 Present: the scale tips 6:02 Present: who survives when the forest changes 7:11 Future: but what about juniors? 9:25 Future: where AI can't go — the field and its context 12:27 For you: juniors, seniors, and people who hire 13:44 EPILOGUE Try it yourself Write down three tasks you handed off last week. Next to each, note whether you handed it off because you couldn't do it, or to hand off the coordinating. The ones you couldn't do — but could now finish with AI — are where you'll grow.
