In a universe with a tech-heavy Themyscira, is there anything they want to trade with the outside world for? I mean, the world would love the purple ray. But what would they need/want? Just because they are more advanced doesn't mean they have all the same things. But what they developed would been along the lines of their wants and needs. Maybe some foodstuffs for variety, because people really do love trading food all over the world. But with such a small population (though I really don't know how big it is), that's not likely to be a great sale, considering shipping costs. Silk and rubber, maybe?

For my headcanon version (as comic versions are so variable), I don't really care if they want to trade or have an embassy or whatnot. I'm just trying to think what they'd want if they did want anything.
