iPhones are for people with more money than brains.
I would be more interested in a correlation with intelligence. Or with tech skills.
1. repulsor beams are more energy efficient, so they are likely to be used first;
2. this device repels, so is kind of like a repulsor beam;
3. a true repulsor beam or tractor beam is gravito-magnetic, not sonic;
4. a true repsor beam will generate an off axis tractor beam of equal power, but with that power dispersed over a wider arc (most likely a full 360 degree dispersal in the plane perpendicular to the beam, with additional dispersal above and below that plane), so there is a small possibility of using that tractor beam for a secondary purpose. That is the most likely way tractor beams will be used.
I completely agree. If they were motivated to learn, they would have done still so on their own. That's the thing with IT, self teaching (especially when you already know the management frameworks and principles) is not only easy, but the most effective way to learn.
You are wasting your time. If the work is not there, they are redundant. Act accordingly.
(IAAL, but not your lawyer. See your own lawyer to make sure you do this right and don't risk a claim. I was in IT for 20 years before becoming a lawyer, including at executive management level, so my evaluation of that part comes from direct experience)
His statement might be right (and probably is) but there is no need for him to express himself that way. He's not a teenager anymore, he's in his late 40s and ought to be able to better control his impulses (or even be centred enough not to have them in the first place). His words would carry far more weight of he expressed himself more maturely.
You had mail, but the super-user read it, and deleted it!
