1. slot screws
In the beginning of the 19th century, screws started to be mass-produced and usage became widespread. It wasn't until the end of the 19th century, that drives other than the slot drive could be easily machined on the screw head. By the beginning of the 20th century the Hex and Philips drive became popular. Finally there was no reason to use the vastly inferior slot drive anymore.
The slot drive slips easily. It can't handle much torque. It has extremely poor grip if the driver mismatches. It deforms easily such that it becomes unusable almost instantly. It is virtually impossible to use safely with power tools. Regardless, people didn't really cease to use slot screws until the 1990s or so. And you can even still buy them today. Although they should have been outlawed a long time ago.
Can you imagine that manufacturers had modern plastics easily and readily available since the 1950?; but from 1950 to 2010 - for no reason at all - they would still choose to insulate electrical wires with cotton weave and natural latex rubber. So that common wires in houses and appliances can't handle much wear and tear, do short out more often and sometimes easily burn up in flames. Just like 200 years ago.
All damn right this would be considered a crime. A crime against people themselves.
When drawing on a piece of paper, did you ever get bored of the fact that the pen draws exactly wherever your hand moves it to be?
Maybe it could be different, yes, it could be even better than this! Imagine, you moved your hand 10cm to the right. But the pen wouldn't always just move 10cm. It would instead move an near-unpredictable amount each time, which is determined by a logarithmic function with linear cutoff thresholds - mixed with other functions of mysterious polynomial qualities - that have half a dozen of input variables and totally change upside down if you switch the paper or pen or do things ever so slightly differently. You move it 10cm, it moves 5cm, or 6cm, or sometimes 9cm. Because it is better this way, more accurate. How you really desire it to be. You just don't know it yet.
Pointer acceleration will be the next big thing in VR camera control. It will as well be forever enabled as default.
