You can't understand anything completly.

Not people , things , places or concepts. no matter in how much detail they are explained because it all interconnects and is relitive to the viewer and changes in there minds "human error". Computers are the best humans? at least they see the error, <most computer errors are caused by loops.

concepts are failed by the lack in the human language tho the detail more the better we still cant communicate properly.

If we had ESP civilisation would be exponetionally more progressed by now.

hopefully we will one day have ESP computers.

Primitive man could see further , because we waste our eyes on computer screen and shopping.
