[MCU] The Asgardians, an incredibly advanced species, couldn't find a way to safely remove the reality stone from Jane. So how did Tony, with comparatively lesser technology, do it so easily?

In TDW, the Asgardians made a big deal about how it would be extremely difficult to safely separate the reality stone from Jane. And yet, in 2023, Tony managed to create the technology to do it, with relative ease; how?

I think it's a combination of three things: 

First, the Asgardians had *very* little time between rediscovering the Aether and being invaded by Dark Elves. Nobody had seen it for eons. The knowledge Odin inherited was a flat-out lie regarding whether the Aether still existed and certainly did not include details like how to remove it. 

Second, there was little incentive for Odin to extract the Aether while it was contained. Removing the aether may have been a very bad idea without a sure way to destroy it (a mistake Thor makes later on). Odin would have had no problem sacrificing Jane if necessary. He regularly sacrifices Asgardians to achieve goals and he values humans far less.

Third, the Aether has its own intent and seemed both hostile to Asgardians/Humans and 'friendly' to the Dark Elves. Two Asgardians got thrown across a room just for touching Jane while it left willingly for Malekith. It's possible that this was taken advantage of in some way to extract it or, at least, that Malekith possessed the knowledge of how to control it (indicating that it was a matter of technique rather than pure technological ability).
