Accuracy and precision are not the same thing...
Please give us a simple but scientific definition of each.
I teach high school science, and I currently use the darts analogy but next year I want to find definitions that are either more accurate or more precise...
I assume Mr. Ford has not been around enough heavy equipment to that you consider it live unless you can see the lockout.
Harrison Ford was self-taught professional carpenter. This was probably his best paying, consistent job as he was trying to make it in Hollywood as an actor. So you would think he would know about the potential dangers of machinery, but maybe he mostly used hand tools. Maybe he's gotten soft and careless.
As a side note, it seems that with its emphasis on practical effects, real sets, and locations, that The Force Awakens was a dangerous film to work on. Mark Hamill almost fell to his death off of the island Skellig Michael shown at the end of the film.
Games like Super Mario Bros. got it right with the ability to have extra lives, but forcing you to start from the very beginning if you run out.
While it is not in the Super Mario Bros. NES manual, anyone who owned an NES in the 1980's knew that pressing A+start on the start screen let you continue from the same world you last reached. (ex. died in level 8-2; continue in level 8-1). These secrets were sold in Nintendo Power and strategy guides, but most kids would share them with each other in class or when they went to there friend's home. Even without GameFAQs back then, everybody knew about A+start, the Konami code, and Justin Bailey just from word-of-mouth sharing.
The reason is that cockroaches are already near perfect for what their niche is. Scavenge for food of any kind and reproduce like crazy. It can take several foot stomps to kill some cockroaches.
The truth though is that all 3 of them have evolved and even had spin-off species, but overall their phenotypes are much more stable than birds or mammals over the same time-span.
I can think of lots of lucrative non-game applications for good VR.
1) virtual tourism - digitally scan all of the exhibits, and background aesthetics of rooms and exteriors in the Louvre. Charge art students / fans $50 per day to visit the museum online. It's cheaper than a trip to France, takes in more money per day, and helps those planning a real trip figure out where to go and what to see in advance. Eventually cities will offer tours of their historical districts complete with local flavor "AI characters" and optional amounts of fellow tourists.
(And if you listen to most people the real life crowds is one of the main things that hold back enjoyment in these touristy destinations).
2) high end real estate tours - probably only worth it for 1,000,000+ (USD) homes and high end office space, but there is surely a standardized way to be discovered to quickly and cheaply scan the textures, geometries, and views in a house/building and translate the data into downloadable/streaming "level" that potential buyers/leasers would want to see without driving all over just to find their perfect place. Upsides include that the hardware could just be purchased by the real estate agent that is assisting the buyers. The sellers would pay to have the location scanned and uploaded - just another advertising expense that is necessary to get the place sold.
3) being "in the middle" of a live event - Instead of sitting 1 km away from the stage at a concert or the field at a sporting event, fans will stand where ever they want. A 3D model of the live event will be constructed by software processing numerous HD camera feeds (probably the hemi-spherical kind) that now hang from the ceiling and stand at intervals among the audience and sidelines. "Sold out" will now mean that the servers are at capacity.
All of these applications are things that mainstream and affluent people would probably spend money on if the experience were good enough. Furthermore, except for the scanning and processing aspects, the actual digital delivery has just the same technical requirements of an MMO with high-end graphics combined with the Occulus Rift (which will be rebranded Being There (TM)).
Will Facebook do this? Do this without having onerous privacy/advertising features? I don't know.
