  • First people didn’t really understand computers, so we taught about them to children - back in late 90’s when I was in school, we had a few school years of dedicated computer classes every week.
    People then started to assume kids just “know” computers (“digital native” and all that) and we stopped teaching them because hey, they know it already.

    And now we are suddenly surprised that kids don’t know how to use computers.

    From experience printing a bunch of different planters with varying settings and printers, without post-processing/sealing the answer is “not reliably”. You can increase your chances by using many perimeters and surface layers, high heat, and thicc extrusions, but you are still just stacking swiss cheese slices on top of each other hoping the holes don’t line up.

    With days submerged, even the tiniest of defects means water can and will seep in.
