His comments indicate vision. Decades ago it was necessary to have caching and virtual memory, but with modern chip design he sees that it's no longer needed; instead of trying to fix yesterday's problem with yesterdays solution let's move on to solving the problem as if there was never a need for caching and virtual memory in the first place.

Language is hard. Even if you aren't translating between two of them.

The "robot" is operated by a human surgeon. Think arthroscopic surgery versus open incision.

That's apples to oranges - you can't compare the malfunction rate of the robotic device when a robotic device isn't used

What you can compare is outcomes, how often the patient recovers without complications. Robotic surgery is a clear winner there

There is plenty of evidence that the "minimally invasive" nature of robotic surgery means fewer infections and faster healing. Overall it's significantly better, but there's obviously still room for improvement.

Another red flag is someone with a PhD in some technical field (say geophysics) looking for a job in some unrelated field (i.e. Linux and Unix systems, whatever that means). The education would get the person past an HR screening, but in person I wouldn't be surprised if that person turned out to be a whacko.

No, the bigger problem is someone being burned alive because a drone interfered with the firefighting.

That's your opinion, Which is worth what you charged for it.

Why bother taking pictures? Most phones can store files the same as a thumb drive

Yup. I worked in a place where they searched briefcases and women's purses. Phones, mp3 players, etc. were left at the door. Coming out they searched again to make sure you weren't carrying any classified papers.

The searches were mostly to stop someone from inadvertently bringing a device in and getting caught with it (it would be destroyed); you have a clearance so they trust you will try to obey the law. Of course if someone really wanted to they could smuggle something in the way Snowden did.

What happened on Okinawa between April and June of 1945 was a foreshadowing of what would have happened if the main island of Japan was invaded. Hirohito thought the allies wouldn't dare invade the main island because of the losses they would suffer; he didn't care about Japanese losses. When the atomic bombs were dropped he realized that the Allies could crush him without significant losses. That ended WWII.

In Philadelphia, the traffic reports would often mention backups caused by "Roving Pothole Crews". It's bad enough when you know where a pothole is, but when they take evasive action it gets really tough.

Not really. Meta-materials can be made with a variety of properties. Some science fiction buff made a long stretch to compare them with a mythical material in an old movie. But what the movie predicted (quite obvious really just a super hard, transparent shield) and what meta-materials really can be made to do are entirely different.
