The most important parts of Intel’s new Vaunt smart glasses are the pieces that were left out.

There is no camera to creep people out, no button to push, no gesture area to swipe, no glowing LCD screen, no weird arm floating in front of the lens, no speaker, and no microphone (for now).

From the outside, the Vaunt glasses look just like eyeglasses. When you’re wearing them, you see a stream of information on what looks like a screen - but it’s actually being projected onto your retina.

This looks amazing. I'm not entirely sure if I, personally, have any use for this, but such basic, simple, handsfree information could be invaluable to, for instance, construction workers, farmers, police officers, or other people who do hard, dangerous work with their hands.

Sometimes it is needed to learn the basics of a subject before you can build on top of it. This is in particular important in math.

Those tests can rarely be realistic as usually the basics are automated in computer programs and tools. If you allow someone to google the solution they will often find the answer, but that doesn't mean they understand why the answer works or could create it from scratch.

Sure, I agree with that, we need to understand how pieces fit together, but I would suggest this is a already a pre-existing problem in the way schools teach today (or at least as I experienced it). Grading incentives can encourage short term memorization over analytical thinking.

I doubt most teachers were ever trained to teach effectively with computers, but I actually think given the right tools it could be highly effective in increasing understanding of the subject over traditional pencil and paper and one way presentations. Even when you've learned the material enough to solve problems on a math quiz, a solid understanding of how variables interact with each other can remain elusive. For example, I "learned" the euler equations and tayler series in school but it was vague and I didn't truly grasp them until later in life with better visualization tools at my disposal. I have more confidence in my own understanding of them than I had in school even though I was able to solve the equations.

For people like me who learn best with a hands on approach, there's simply no textbook alternative to using a spreadsheet/numerical analysis/cad program to truly interact with the data. Personally, I learn better with technology than without; I suspect many people are the same way. Moreover, those who mastered problem solving with technology will be far better situated for the professional world than someone who's merely book smart with formulas that can be looked up. I plan to teach my own kids complex math using computers, should they express any interest ;)

You do raise valid concerns, but IMHO it's nevertheless a net benefit. Anyways, enough of my opinion, I was curious what others think, thank you for your opinion! I totally hijacked the conversation, but I don't have much to say about intel's smart glasses haha.
