    Their wordsBorn of simulation, now used for everything, even when inappropriate

    Locking is too hard for programmers to get right over and over again, so the language runtime should do that part.

    Choosing what is easy over what is simple buys speed only at the start, the way only a runner in a very short race can sprint from the gun.

    simplicity

    Their wordsSo, what kind of runner uh can run as fast as they possibly can from the very start of a race? Right. Only somebody who runs really short races.

    Simplicity is a choice, and a system that is not simple is its builders' fault.

    agencysimplicity

    Their wordsThe bottom line is simplicity is a choice. It's your fault if you don't have a simple system.

    Simple and easy are different things, and treating simplicity as ease of use is a mistake.

    simplicity

    Their wordsYour sensibilities about simplicity being equal to ease of use are wrong. They're just simply wrong. Right? We saw the definitions of simple and easy. They're completely different things. Right? So, easy is not simple.

    Tests and type checkers are safety nets: they do not make a system simple, so they cannot touch the core problem of understanding it.

    developer toolssoftware quality

    Their wordsRight? They just do not touch the core of this problem. Right? They're safety nets, but they're nothing more than that.

    Simplifying often leaves you with more things, not fewer: simplicity is about not tangling things together, not about counting them.

    simplicity

    Their wordsAnd recognize that when you simplify things, you often end up with more things. Right? Simplicity is not about counting.
