Not true. I can think of many cases where they're wrong, but I can also think of many where they're right. With cameras and suchlike you're running limitations of physics, as far as image acquisition is concerned; the other issue is that there's a huge body of knowledge on how to move a camera properly, whereas a head-mounted camera is kind of painful to watch because you don't have the kinetic cues to go with it, and every little twitch or movement of the head becomes a distraction for the viewer who has to filter out the irrelevant movements in their visual cortex. Look at all those videos on youtube where people don't know how to hold a camcorder and it is just waving all over the place even when they're aiming it at a static object in front of them.
The musical instrument world is abuzz with new analog synthesizers right now, because over the last couple of years several major manufacturers have just gone back to manufacturing it because SMT and FPGA/FPAAs have made it affordable to do so again. They're still making DSP synths because DSP still offers many advaantages (not as noisy, fewer limits on polyphony, vastly cheaper at scale), but analog synths are huge again because they simply sound more interesting to most musicians than their digital equivalents. I'm about to sell one of my DSP boxes for this very reason, in fact.
