The Wizard of Oz was an old guy hiding behind a curtain though. Luke really is a space wizard.
It’s all a matter of degrees. I would argue space wizardry has had a serious demotion in the ST, both in terms of what we can expect of it, and in terms of what it takes to become a space wizard.
I don’t know that feats of the Force have gotten more or less impressive in the ST, only that they’ve changed.
It’s true however that according to the ST you can become a powerful Force user in about a week.
