When I read the book Ready Player One, I really got excited about the future of virtual reality, but the movie really didn't do the book justice. Some blockbusters have succeeded in interspersing computer graphics with real people and making it hard to tell the difference. Still, a totally rendered movie still looks like animation and you just don't get the film quality you get from, well, film.

Tesla is trending to fail spectacularly. It has been burning cash at an unsustainable rate, and it keeps making avoidable mistakes that weaken it. Here's what is weird: You'd think the firm's biggest problem would be that every large car maker was working behind the scenes to kill it. However, the car companies for the most part appear to have worked harder to emulate Tesla than to destroy it.

There are many interpretations of Salesforce's elevation of Keith Block to serve as co-CEO with Marc Benioff. Block has been the company's vice chairman and president for several years, and the elevation could be a recognition of the obvious -- he's been doing the job without the title for a while. However, Salesforce and Benioff are well known for getting added mileage from any move they make.

Apple is one of the most popular and powerful companies in the U.S., and last week it became the most valuable as well. That news brought back some personal memories of my time at IBM, when it was the most powerful and valuable technology company in the world. For a long time, it seemed virtually untouchable. However, IBM went off the rails, and by the early 1990s the stock had collapsed.

I just finished The Fourth Age: Smart Robots, Conscious Computers, and the Future of Humanity, and it was one hell of a read. A lot of us are concerned about the coming of robots that arguably will be substantially smarter and more capable than we are. This book likely will make some feel a tad more comfortable about the future, but others will have to brace for change.

Swings Bluetooth Earrings with built-in earphones showcase a practical, clever idea for people with pierced ears. Swings certainly could fix the problem of losing Apple's expensive AirPods to the ether or having to root around in one's pockets or purse to find one's tangled-up headset. You can expect five hours of listening time out of the Swings on a single charge.

For pretty much my entire career, CEOs have been almost invulnerable. Even when Apple founder Steve Jobs tried to get then-CEO John Scully fired from Apple, he lost and got fired himself. I've watched CEOs at companies with zero-tolerance employee dating policies have affairs with subordinates and get a pass. Things have changed. Almost every week, another CEO bites the dust for misbehavior.

Samsung plans to launch a foldable-screen smartphone early next year, according to reports, possibly priced around $1,500. It will resemble a book, with the main display inside the covers, said Ken Hyers, director of the emerging device strategies service at Strategy Analytics. The exterior will have a smaller notification display on the front, and a camera, or cameras, on the back.

Microsoft Inspire is taking place this week, and a huge number of my personal friends and I were prebriefed on what the big announcements would be. Strangely, the embargo on the news lifted last week, so I'm not going to get in trouble for sharing some of the revelations. There are a number of interesting elements, including Microsoft's suddenly aggressive move to use Azure as an IoT host.

It's interesting to compare Google and Amazon -- two of the most incredibly powerful companies in the world. Amazon brings out product after product, with more successes than failures. Google largely buys companies and then loses interest in what they do. Profit is built into Amazon's retail efforts, while Google largely lives off selling users' information and providing access to content.

Tech companies have been going through a lot of CEOs of late. HP had a revolving door for CEOs with mistake after mistake. Yahoo's board kept making choices that made things worse, Uber's CEO almost took the company under, and CEOs fired for ethical lapses jumped a whopping 36 percent. When an employee misbehaves and has to be fired, it generally is at least partially the fault of management.

Apple plans to expand its audio product line next year with new AirPods, HomePods and possibly studio-quality over-the-ear headphones. The new generation of AirPods will feature noise cancellation, be water resistant, and have greater range, according to a report citing people familiar with the developments. Apple's plans reflect an expanded role for audio in the company's future.

IBM just showcased Project Debater, and it just won against a top human debater using actual facts. We need the production version of this tool yesterday. The problem with fake news is that it is getting worse over time. We have always had issues with politicians and con artists trying to convince us down is up and to get us to do things that, were we informed, we'd never do.

Amazon's latest gambit for taking over your living room is the Fire TV Cube. It works in much the same way as the Fire TV stick, but with the added impact this time around of stuffing in a smart speaker with the familiar tones of the Alexa voice assistant. You can use it to play whatever you want to see in up to 4K resolution from various streaming services.

To say we live in troubled times would be an understatement. It often feels like the politicians and executives who surround us are interested only in who can tell the biggest whopper while lining their own pockets and leaving their constituents and customers to pay the bills. I recently read that the real reason Jon Stewart stepped down from The Daily Show was that he was incredibly angry all the time.

Dell's most forward-looking people spoke about the future at Dell World a few weeks ago. One of the sessions I attended dovetailed with something that appears to be glaringly obvious -- to me, anyway -- which is that is that robots likely will be the next big technology wave. I then wandered around to find out what Dell was doing in robotics, and I couldn't find anything. Dell is not alone.

The most popular show on ABC was canceled last week because the star of the show, Roseanne Barr -- known for saying and writing stuff that would get most of us fired -- did exactly what she was known for doing and got fired. ABC now looks like it is run by idiots because, really, who didn't see this coming? This outcome is one that could have been prevented relatively easily.

I got a view of the future at HP's Innovation Center in Barcelona. The company has made some aggressive moves to blend its printing and imaging technologies to create products that will redefine our near-term future. HP also showcased capabilities that are something just short of magic. When you can transform what you can imagine into physical products, what else would you call it?

Apple has ramped up production of its new 7-nanometer processor for its upcoming crop of iPhones. The new processor will be smaller, faster and more efficient than the 10nm processor in Apple's current iPhone line, according to a report. Taiwan Semiconductor Manufacturing Company, one of Apple's partners, has begun mass production of the chip, which is expected to be called the "A12."

Cisco has reduced the poaching of endangered rhinos in Africa by a whopping 96 percent. This success comes at a time when kids appear to be increasingly at risk from rogue school shooters and the United States government seems deadlocked on gun control. The focus of Cisco's tech is on catching the poachers who kill around 1,000 endangered rhinos a year, rather than on taking away their guns.

Microsoft plans to release a line of Surface tablets priced in the $400 range later this year, according to a report. The tablets are expected to have 10-inch screens and rounded edges, and USB-C connectivity -- a first in Microsoft tablets. They will be about 20 percent lighter than the Surface Pros, and their battery life will be about four hours shy of the 13.5-inch Surface Pro.

I've become convinced that too many of us don't prioritize our employment choices properly. What recently drew my attention to this was a conversation I had with Dell's CFO Tom Sweet at Dell Technology World. We were chatting about Dell's problem attracting employees. Because Dell is a private company, few employees get stock or stock options -- they get cash instead. It seems that has put Dell at a disadvantage when competing for top folks.

I recently attended Dell Technology World, which shone a light on one of Michael Dell's passions: addressing the lack of gender diversity in the tech industry. Some time back he asked the most powerful woman at Dell, CCO Karen Quintos, to spearhead an effort to fix the problem. One of the leading experts on the problem, Howard Ross of Cook Ross, indicated it was getting worse -- not better.

I spent a day with BlackBerry last week and it brought back memories of how Apple displaced the company around a decade ago. I, like a lot of folks, thought what Apple was attempting was impossible. However, after the fact, it didn't even look difficult. BlackBerry largely has completed its pivot to software and services, but a wave of new phones from its partners suggests new possibilities.

Amazon could bring a home robot to market as early as 2019. Codenamed "Vesta," after the Roman goddess of home and family, the project is several years old, but hiring for it recently has ramped up with an eye toward placing prototypes in employees' homes this year. The robot could be a mobile smart speaker. Some versions of the product apparently have cameras and computer vision software.

Two new initiatives -- a concerted effort by Apple and a massive educational effort called the "Pro-Truth Pledge" -- could help eliminate much of the fake news BS that is really messing up the U.S. at the moment. On another front, President Donald Trump's plan to meet with Kim Jong-un reminds me of a pivotal meeting between former HP CEO Carly Fiorina and then Apple CEO Steve Jobs.

Not quite content with furnishing every other aspect of our homes, IKEA has continued its push into smart home territory with its first Bluetooth speaker. The Eneby comes in two sizes: 8 x 8 and 12 x 12 inches. You can use it as a portable speaker with up to 10 hours of battery life with the optional $20 battery, and there's a handle for added portability.

After I considered Facebook CEO Mark Zuckerberg's testimony before Senate and House committee hearings last week, it became very clear to me -- and I expect many in Congress -- that social media companies need to be regulated. However, I think this is only a step in the path that governments -- and I do mean more than the U.S. -- will take to ensure their effectiveness and protect their people.

Facebook reportedly allowed CEO Mark Zuckerberg and other senior executives to delete messages from recipients' inboxes and chat threads, but it did not disclose the practice or offer the same capabilities to users. Facebook began using the tool after the 2014 hack of Sony Pictures to protect executive communications. Facebook later said it would make the feature available to all users.

The shooting incident that took place last week at YouTube had less to do with guns than with the failure of the police to act on information in a timely way and the inability of social media to be anything but part of the problem. Google has been giving this issue little more than lip service, but I expect it has become motivated to do more, given that YouTube was the latest target.
