The VR optimists underestimate how deeply human it is to manipulate a tool with your hands. It's not a coincidence that the only intelligent mammal is also the only one with opposable thumbs. If voice was actually vastly preferable to the output of a keyboard, it wouldn't be the case that texting is more popular than calls (and that voicemail has more or less gone the way of the betamax).

Are you being sarcastic? I do this every day in Google docs.

But that's exactly what VR enables. Instead of clicking a button to swing an axe, in VR you can naturally swing that axe with your own hand. Instead of dragging a mouse to draw a line, you can just move your hand. In many cases VR allows to skip that layer of indirection between input (keyboards/mice/joysticks) and output (screen).

I agree. This is exactly the sort of inconsequential activity where VR will really excel.

Dragging a mouse is "just moving your hand." If you really need less friction in this case, use a touch screen. What do a VR headset and VR hand tracking gloves add?

I like this point, and I think it might illuminate where the fundamental disagreement is: how many of these cases are there? For most of the things I do with my computer (writing code, email, listening to music, reading articles) I am simply not convinced that there is a layer of indirection. Keyboards, graphical user interfaces, and CLIs are already well-optimized for ease and efficiency in achieving their stated goal. Introducing VR would increase friction rather than remove it.

I don't think your objection diminishes my main argument, which is that many forms of communication don't receive any optimization from VR - including forms that the VR crowd seems to believe will be revolutionized (e.g. wildermuthn's whiteboard example).

Texting is preferable to voice only when it's a break from human interaction.

That's why you call your parents but text the girl you met last weekend.

It's not because they're too old to text. If the only way they could communicate with their children was through text, they'd be typing on their phone more than a stereotypical teen. It's because you're comfortable talking to your parents. Even when it's at it's most-uncomfortable, it's still familiar, safe, and never going to be as bad as the painful conversations you've already had with them. You don't need the safety net of putting the phone down, distracting yourself from the conversation by stressing about the conversation, procrastinating, or the flexibility to workshop every response with your friends.

For human interaction, voice is vastly preferable.

This is trivial or false. If you define "human interaction" as "the sorts of interactions where we'd rather talk" then sure, voice is preferable by definition. On the other hand, if you define it as "interaction between humans" then your own example shows that it depends entirely on the nature of the interaction. Sometimes we'd rather talk and sometimes we'd rather text.

I should have originally written "If voice was _always_ preferable to the output of a keyboard". I'm obviously not suggesting that there are no cases where voice is better than sms.

What I'm suggesting is that our existing text/chat messaging, CLIs, GUIs etc are much more than a crude approximation of moving things with one's hands (or speaking) which will be obviated by VR. They are, in the appropriate cases, _more_ easy and efficient than moving things with one's hands or speaking.

But not every technology ends up being the next personal computer, cellphone, or Facebook. Someone probably once thought that hosting sites like GeoCities were the future before blogs/Facebook made it clear that the average user doesn't want to design their own website. It took something more approachable to come along.

Yes, chalkboards, I’ve heard of them and used them.

Yeah, sorry, but that’s just not how most real work gets done in the real world.

Make Excel a compelling VR app, then we’ll talk.

Is this really such a common way to work and collaborate? I’ve rarely seen this even in co-locates teams. More usually problems are such that people work offline, put and document/proof-of-concept, presentation together and then maybe discuss the presentation/document verbally, or over email.

Not so much movie style enthusiastic whiteboarding. Maybe that would be better way of working, but is it really that common? Is there any data on this?

Same observation: it absolutely isn’t how people work & collaborate. VR is DOA for most kinds of work because it just isn’t all that compatible with most kinds of work.

Why will VR be a better solution for this than AR? Surely being able to see your real surroundings with virtual whiteboards and controls 'stuck' to various surfaces will be more comfortable for people than a totally immersive world.

I don't know anything about VR and the biological costs of using it, but why is it necessarily more harsh on the body than glasses and headphones and gloves? Future-VR is likely to get smaller and lighter, like current VR is smaller and lighter than Steve Mann's 1980s and 1990s wearables. Won't there come a point where it's just .. light and easy and mostly fine?
