Intentionally being obtuse because they cant actually point to anything that is magic. Not consistently at least. 

Pyrokinesis to the point of actually causing damage by harnessing some kind of aetherial energy. Or creating objects wih your mind and maybe some gestures. Mind control. Yes you can achieve all of these outcomes with tech, but that doesnt make it magic. It makes it tech. Some retard is going to hop on me about how the more you understand a process the more it leans towards tech and ergo things that were once magic are now tech because its all perspective. No. 
Magic would be something like a dude actually using telekinesis to levitate an object around the room. 
Tech is fitting the room with magnet relays and selecting an object to fit it with reverse polarity magnet facing down cooled to beliw freezing so it floats. 
Shit is not the same.

To get an idea,  is also my post trying to explain vaguely what magic is to me. I dont have a proper working definition on the matter and i know it's not genuine to day shit like 'you know it (magic) when you see it' but so far thats how i feel about it
