Segment 1 — The Cold Open
In the 1890s, closing a boot, a skirt, or a tobacco pouch still meant a row of tiny hooks and eyes, each one formed separately, each one set by hand, and each one ready to snag fabric or pop open the first time the cloth was pulled sideways. ...

Segment 1 — The Cold Open
Before the electric washing machine reached ordinary homes, a typical load of laundry demanded hours of lifting, soaking, rubbing on a washboard, wringing, and rinsing by hand. The labor itself was the dominant cost, measured in human time rather than dollars. ...

Segment 1 — The Cold Open
A four-year degree at many private colleges now carries a sticker price above one hundred twenty thousand dollars.

The cost of moving one passenger one mile fell from hundreds of dollars in the Wright Flyer days to a few cents by the DC-3, because designers stopped copying wood frames and started from the strength of aluminum sheet.
Segment 1 — The Cold Open
In 1903 the Wright Flyer carried one person a few hundred feet at a total build cost measured in thousands of today’s dollars, with most of the expense locked inside hand-shaped spruce spars and hand-stitched muslin. ...

A generic pill whose active ingredient costs pennies to synthesize can still cost patients hundreds of dollars a month.
Segment 1 — The Cold Open
A finished tablet whose core chemistry can be assembled from commodity reagents for well under a dollar per gram still reaches pharmacy shelves at prices that multiply that figure by tens or hundreds.

Transistors that once cost dollars each now sell for fractions of a cent because engineers reduced them to the price of silicon and a few dopant atoms.
Segment 1 — The Cold Open
In 1950 a single vacuum tube that could switch or amplify a signal cost several dollars to build and install. By the late 1960s a single transistor performing the same function inside an integrated circuit cost less than a penny, and today the figure sits well below one-thousandth of a cent. ...

Segment 1 — The Cold Open
A standard adult funeral in North America commonly runs between seven and twelve thousand dollars once the casket, embalming, viewing room, transportation, and paperwork are added together.

Before the barcode, every price at checkout had to be typed by hand; afterward, a laser read an identity printed in ordinary ink for a cost approaching zero.
Segment 1 — The Cold Open
In the early 1970s a supermarket checkout required a clerk to read each price tag and press keys on a mechanical register, one item at a time. The physical limit of that process was set by human reading speed, finger movement, and the chance of misreading a label. ...
