It may well be beyond my current skill level, but all the evidence I've looked at suggests that this is possible. I'm not sure how to pull it off, but it's the best way to show magic to the world in a way that can't be refuted or ignored.
Looking forward to see how things might go wrong just means that I don't yet have real confidence in my abilities, and somewhere deep down that was already known. It'd be an act of pure stupidity to charge ahead with false confidence only to see the platforms crash from the sky or evaporate back into thin air because I wasn't actually ready to handle it on an emotional level. This could have been a real disaster if it'd gone on too long—with entire floating cities resting on the wellbeing of a single mage. We don't need magical foresight when there are huge and obvious glaring flaws in the idea.
Still useful to demonstrate magic, of course, but needs some serious planning to be actually useful.
