LinkedIn was supposed to make professional networking easier. So why does it now feel harder than ever to actually reach anyone?

In this episode, Jeph and Shingi explore The LinkedIn Effect how a platform that once felt like an obvious breakthrough slowly turned into something we all rely on but rarely enjoy. From the early promise of frictionless professional connections to the reality of ghosting, performative posts, and expensive premium tiers, this is a behavioral deep dive into what happens when networks scale beyond meaning.

Blending psychology, technology history, and cultural insight, the episode asks a simple question with an uncomfortable answer: when does a useful product stop feeling useful — and what keeps it alive anyway?

A witty, reflective look at the professional network we can’t quite quit.

Episode Description:In this episode of The Deep Dive, Jeph and Shingi explore a technology that has stood the test of time: the train. While the US pivoted to the car, allowing the "Golden Age" of rail to fade , Japan doubled down, creating the high-speed Shinkansen to unlock a new kind of suburban development.

We break down the "Great Divergence" between American and Asian transit strategies and analyze the brilliant "Rail + Property" business model used in Hong Kong—where the transit operator acts as a real estate developer to fund expansion without massive government debt. Finally, we discuss the behavioral economics of rail: the "chauffeur experience" of zero cognitive load and why living in New York can be cheaper than Utah when you delete the "Car Bundle" from your life

The washing machine and the dryer are the quiet geniuses of modern life inventions so transformative that we barely notice them anymore. In this episode, Jeph and Shingi explore how humanity went from rivers and washboards to electrified drums that liberated billions of hours of labor.

From Jacob Christian Schäffer’s first hand-cranked washer in the 1700s to Alva Fisher’s electric Thor machine in 1908, from George T. Sampson’s heated-air drying drum to the heat-pump and sensor based dryers of today, this is the story of two machines that reshaped society more than the internet ever could.

But this isn’t just a timeline. It’s a behavioral journey. These machines didn’t win because they cleaned better. They won because they changed how people felt about time, effort, and control. The washer freed labor. The dryer freed uncertainty. Together, they redefined what “modern life” even means.

A witty, reflective deep dive into the household innovations that quietly moved civilization forward. Perfect for fans of behavioral psychology, technology history, and hidden revolutions hiding in plain sight.
