Just like the computer is 'dead' when it's switched off. But that doesn't mean the user of the computer is dead. He just walked off to somewhere else. He may also start using another computer.
The body dies when it is dead. The brain goes along with it as well. The brain is not the user of a computer, but rather the result of the device. If the mind were the user then we could not affect it so easily through affecting the structure of the brain. Obviously if we can affect the mind through the brain, then they must be linked and given the nature of the physical machinery of the brain, the most likely idea is the mind is the result of the brain.

A large part of the world's population believes this. To me it seems quite reasonable too. I haven't ever seen a computer build itself or switch itself on (unless a human programmed it to do so) - that's what I find missing in the metaphors that compare humans to machines.
Human beings are more adaptable than computers and use better technology than machines, also human beings never turn off. They sleep but they never stop. The points you bring up do not display that human beings have a different philosophical quality but only that they are physically different.

The same goes for the recent so-called 'progress' made in the latest scientific fad, the neurosciences: just more detailed descriptions of mechanisms, but nothing basically new (just measure something a bit more precisely, and you can fool people into believing you've done something totally new. You don't need any new arguments, new insights, nothing but a measuring tape with a few finer lines on it) - which is typical of Western thinking for about a hundred years now: there's so much infatuation with the glitter and glamour of machines and devices and measurements and statistics and quantities that those folks who dare ask questions about things like meaning and quality are considered to be not quite of this world - wrong planet, so to say.
Progress does not need the apostrophes. What we do through better description is still worthy of the term as we better understand how the device works and how to manipulate it as we desire. We learn better drugs to change its processing, we learn about psychology and how people act, we learn about its nature much better through our measurements and better knowledge is a new thing. We still get insights from our acts as well such as the evaluation of old psychological theories and of mental processes. Meaning and quality are useless questions from the role of logic, we can argue what systems do and their results, and we can discuss the quality of statistics and rigor of analysis, but we cannot logically come to any conclusion on human meaning, nor can we come to any conclusion on what quality is to a human being. These questions ultimately fall down to individuals to answer for themselves, as western civilization has recognized an inability to objectively answer these questions and sees no reason to focus on a fruitless act.

And that's why dualism is still a meaningful philosophical position. Machines, even the most clever ones, don't care about meaning and quality. They don't care about anything - they just are, and they don't even know it, because they can't know anything. No aspies among the machines either. Since they know nothing, they also don't know what a problem is.
Machines are not as developed as the human brain, nobody denies that, however all the brain is only a very advanced information processing device, just like machines are. The brain is still just a device whose functioning can be altered by physicality and whose functioning was derived from physicality in the first place. There is no reason to even assume a mental plane except our own infatuation with ourselves and our glory. The brain is a physical device and works just like it was designed to, the only difference is complexity and purpose as the brain was designed to deal with the struggles of living and breeding.
