Will mention  - obvious 'pseudo-news wallpaper' (especially as the dates don't match).

I got an idea
Take a piece of metal and make random symbols into them that mean zilch, bury it deep in the ground and 4000 years later make those people wonder if it was aliens.--Rationalzombie94 (talk) 22:38, 14 March 2017 (UTC)
- A variant on the ancient 'annoy the descendants' suggestion above. 22.214.171.124 (talk) 22:56, 14 March 2017 (UTC)
The reality of OOPs
Stuff as the Antikythera mechanism and very likely others mentioned in the article just prove ancient people were far more capable than more people think and capable to design (emphasis on that) complicated machinery. Just that, as designing those mechanisms is one thing and manufacturing them with the techniques existing in those epochs was a far more different one, in terms of both costs and results.
Just like all those manuscripts and books lost at Alexandria's library I'm quite sure there were more artifacts as that, but that have basically been lost forever because they were one (or, at best, a few) of a kind. --Panzerfaust (talk) 14:02, 7 July 2017 (UTC)
- The things which are of 'high status interest' (expensive jewellery, works by celebrity artists etc) are kept and/or written and/or discussed - the ordinary objects are not - have RW users made any note anywhere about 'portable computer memory' (floppy discs, memory sticks etc) and how it changed over time? That they used to eat (x variety of apple) which disappeared and they now eat (y variety). And then there will be the 'trade secrets' eg Coade stone.
- Only a fraction of what is produced at any time survives #and# is written about - and some OOPs will be deliberately so - the 'common item acquired' becomes 'a strange item' (or gets accidentally lost) elsewhere. 126.96.36.199 (talk) 15:40, 7 July 2017 (UTC)
- The records that store said information could have been lost too. Things were quite different in the past, when (very) few people could write and paper or equivalent was expensive, and there were no archeological desires. --Panzerfaust (talk) 20:38, 7 July 2017 (UTC)
- There were craft traditions of not revealing information/skills to outsiders.
- There are various types of OOPs - 'things misplaced, acquired, displayed and traded long distance' (there was some conscious intent in their being not in the expected place) and things for which the technology and context has been forgotten/lost/was not persisted in (the ancient world steam engine not used because it would make the slaves lazy); the Antikythera device being the equivalent of Faberge eggs and the 'showcase books and jewels' perhaps). 188.8.131.52 (talk) 21:20, 7 July 2017 (UTC)
- I think I've seen elsewhere a steam engine that is not a toy needs materials resistant enough and what Greeks had were not for the task. Not to mention they knew little about thermodynamics even if they could have developed the principles had they built them.--Panzerfaust (talk) 00:06, 8 July 2017 (UTC)
- I think this is what is being referred to. There probably always were 'executive toys, demonstration models showing what could be done and presentation pieces' etc (and sometimes 'technology for which there is no/limited present use for a number of/many years' - eg the early fax machines. 184.108.40.206 (talk) 10:09, 8 July 2017 (UTC)
