Sufis maintain the means of attaining enlightenment change according to time, place and people. What might have worked for someone living in 10th century Baghdad wouldn't have worked in 10th century Europe, nor will it work in 21st century Baghdad or 21st century Europe.
Everything changes as time, place and people change. This isn't because the ultimate spiritual destination changes, but because the starting point, with its societal conditioning and general state of technological development, is constantly changing. Where one starts from initially in any time or place is relative and conditioned. A true spiritual guide wants help you get somewhere that has never changed and has nothing to do with where you are starting from, though the journey may be easier or harder depending on things such as cultural milieu, socioeconomic and even idiosyncratic factors of particular individuals.
In short, there's no completely prescriptive way of ensuring that you get from A to B. "A" is peculiar to each one of us. Getting to the water in the well that will save your life depends on where you start your journey from. Some paths are easier than others, and the guide is someone who can map out the one most suitable for you given your current state. There might be a few things that are useful for most or many people (a particular kind of meditation, a particular religion, a particular socioeconomic state), but no two paths to enlightenment will be precisely the same.
The guidance offered won't necessarily appear "spiritual". It may, for instance, involve psychological factors; or the guide may advise you to do a certain kind of paid work. Nor has personal happiness or contentment necessarily anything to do with the price of fish. You may need to be unhappy for a time in order to make progress; happiness might actually be a hindrance for you, perhaps especially if it's based on mainly superficial factors such as a good standard of living, having an attractive mate or worldly achievements/recognition.
The idea that one can get anything permanent from a technological approach to "enlightenment" is one I find highly dubious, particularly if the technology is constructed by someone who has no real idea of who you are/where you are starting from, let alone where you are meant to be going. It seems to me that Dr. Martin is merely providing a set of tools to help people decide for themselves which path to take based on some destination that may be irrelevant, or even counterproductive, to their needs. Even if they find contentment, so what?
Maybe technology, like meditation and other spiritual exercises can help some people in some circumstances. But any technique is merely a means to an end and not an end in itself. The question is, what is that end or aim? Only when you find that out will you know, and at that point you will no longer need techniques. Their only use will be if you are suited to be a guide and you need them to help others towards their destination. Dr. Martin doesn't appear to know what is being aimed for. It's more like he's helping people find for themselves techniques to get them to a destination they think is what they want. It might not be -- could be a complete red herring in fact.
