I remember watching his show in my younger years. I always assumed/thought that 'all magicians hate him' was just to sell the show more, like surely we all know magic isn't real anyways? Apparently that's not the case, it seems.
As a former professional magician and lifelong magic enthusiast, no serious magicians hate this guy. On the contrary, his show was great because it drove interest in magic which is good for working performers. The "Magicians HATE him" shtick was just marketing hype to promote the TV show. Of course there are probably a couple of clueless amateur magicians somewhere out there who will spout about this guy but it's not…
Make a space shuttle disappear[0], or hide an elephant. The TV show revealed all those to be fake and were in fact - paid audiences. My little brain trusted that they weren't paid and wanted to know so bad how the space shuttle disappeared.
Overall the TV and the internet helped push magic to exactly where it is today. Amazing, talented folks who even when you know how it's done, it's so good - it's magic.
