Apple's new Vision Pro headset receives praise from some while raising concerns for others.

Apple is about to release the Vision Pro headset, which James Cameron and Marvel director Jon Favreau have lauded as "revolutionary", however, some have compared the bulky gadget to "digital fentanyl" and a "face-hugging alien."

The revolutionary $3,500 device, developed by Tim Cook and his virtual reality team, is set to premiere on Friday. It weighs roughly the same as five sticks of butter and has been praised for its futuristic capabilities by James Cameron, the director of "Titanic" and pioneer of virtual reality.

“I would say my experience was religious,” Cameron, who has been working in VR for 18 years, told Vanity Fair. “I don’t bow down before the great god of Apple, but I was really, really blown away.”

However, other Silicon Valley investors weren't as enamoured with Cameron as they thought the heavy product—both in terms of weight and cost—would fail to live up to its own hype.

“I’m sure the technology is terrific. I still think and hope it fails,” a Silicon Valley investor, who was not identified, told the magazine. “Apple feels more and more like a tech fentanyl dealer that poses as a rehab provider.”

The gadget is roughly 20 ounces in weight and has the ability to project 23 million pixels into each eye when worn on the head. This is "equivalent of the resolution of a 75-inch TV."

The experience has been characterised as life-changing from a technical standpoint, according to New York Post.

After using the headset for several weeks, a Conde Nast reporter claimed that the enhanced version of reality blinked into his eyes and started to feel significantly less superior to reality.

The CEO of Creative Good, an online strategy consulting firm, called Apple's new wearable technology an "isolating device" and chastised the corporation.
