    Sand to wafers… Fortunately, there is no shortage of raw material. Silicon is the second most common element in the earth’s crust, comprising about 26% and exceeded only by oxygen at 49%. But silicon does not occur naturally in the pure form needed for electronic applications, for which it must contain less than one in a billion non-silicon atoms. The starting material really is sand. Not just any sand, but silica sand, specially quarried for this purpose and having concentrations of quartz (silicon dioxide) as high as 95%.

    It was an Apple ii I think and Star Trek of some sort. ASCII based graphics and words. Idk I was 6. Didn’t have a clue what I was doing. It was on my bio father’s computer. He used it as a way to distract me while Mom and him argued over child support. Last time I saw him thankfully. But at least I have that memory of trying to catch a “k”

    Fuck I’m getting old.
