No. You dont.

There are other metabolic pathways to produce glucose (or produce ketones). The other pathways ‘push’ the body more since they have to do some conversion. This ‘extra effort’ is considered to be more healthy.

It depends, for short input you're right. But if you're filling a whole form with multiple inputs the pen definitely helps.

I do this on the iPad. And it works way better than on the video (latency, hand-resting, ...).

Yes that is simply incorrect, you will lose crazy amount of weight on 500 kcal a day. Maybe it was for rodents?

I think I saw somewhere on hackernews a calculation that for only maintaining you body temp it takes 800-900 kcal. That is not even taking into account breathing, blood circulation, etc.

It guarantees works for everyone. I lost all my excess weight in just 2 months, first time ever in my life going on a diet. And as a physicist I was convinced from the start that a caloric deficit MUST work. It did.

Yes, what I can say it will be harder for some persons than others. The hormonal environment in the body can not be disregarded and can be either disrupted or genetically different. STILL, restricting your eating habit (caloric deficit), will.always.work.

This adopting metabolic rate is way overblown. Yes it does happen, but somewhat slightly. For someone just aiming to lose weight, you don't have to think about this at all. Just be in caloric deficit, and adjust slightly if needed (usually not).

It ALWAYS work for a person not having severe diabetes. In case of diabetes (at least type 2) it might actually help, but care is needed.

Something must be going horribly wrong in Greece. You can live easily of 30k in the Netherlands, I would make that to even 25k. Yes, that would mean having no car and using a bike to get around (which is common).
