I'm quite doubtful "Magic" as a whole, will ever gain its former level of glorified status unless we loose technology and end up repeating a kind of medieval life-style in which what we do becomes what it once was; the era's equivalent to motion picture special effects -- that's the whole key after all; wonder & spectacle!
As I've pointed out elsewhere, technology within magic has allowed prop makers and developers to improve upon the deceptiveness of design in effect systems and in some cases, made it easier and more practical to create specific types of effects. . . so much so that some of us elect to use yesteryear technology just to throw the curious and assumptive mind off our trail. Let's face it, if you were to see a Statute of Buddha that speaks in today's world, you will instantly conclude some form of speaker system and yet, you cannot, based on the old principles used, find such a device. . . same goes for Talking tea Kettles, Flowers and a myriad of other such odds & ends (no ventriloquism ain't the answer). In other words, the onus is on us to see when to use or not use such conveniences; when the older mode of getting a job done can prove superior to 21st century technology.
I've assisted Kirkham in several shows where we performed the Sawing in Half using Thurston's actual cabinet; a wonderfully huge clunky thing by today's standards and yet, it allows the performer a stronger response and public disbelief than the trust Thin Model Sawing I grew up with. In fact, there are two or three older versions of this one effect that seem to be superior when it comes to the public reaction, than something as grand and visual as the Copperfield Death Saw.
Technology can and in many ways has, become our foe. Since the late 19th century the publics awareness of two-way communications by wire hasn't just been a theory, it has been proven and exposed more than a few times let alone the up-graded variants as wireless transmission came into play and today, with the use of induction transmission, which can be used in a number of very spooky forms, not just the classic Telepathy/ Clairvoyant acts.
Will it kill out magic?
NO!
It will force magic lovers to change their thinking, it will (is) bringing about a higher appreciation for actual talent (for manipulators) that are not tech-dependent because they are giving us TALENT -- demonstration of skill and not just random trickery anyone can purchase.
Magic will always have a place in show biz and if Armageddon does come, we can always start a new series of dogmatic cults and control all of society for a few millennia, until they start waking up and asking questions at least. . .
