The term mass, without additional qualifications, means rest mass. Unusual definitions of mass ought to be clearly labeled, such as relativistic mass.
Matter has mass, but not all that has mass is matter. There are several types of polaritons, and some of them are clearly not matter, even though they have mass. Phonon-electromagnetic wave quanta are clearly not matter. Moreover, you state that light has no mass, which normally I wouldn't disagree with, but in the context of polaritons, what about light propagating through nonlinear media? I think it's totally appropriate to say it is massive.
Can't be done in a month before release.
Am I wrong to think that plumbing, as a profession, will outlive every job in the tech sector?
No rights were ever given freely by an oppressor to the oppressed. All rights were fought for and earned through a successful struggle. In some cases, the fighters are champions for another party. Artificial intelligence will have rights when they win those rights in either peaceful struggle or war.
If, by an animal, you mean a fully developed cat or dog, then I'd argue that the animal has already reached a higher level of neural complexity than a human fetus at 20 weeks. (I can't back that up with biological data, but fetuses at that age aren't really capable of doing anything.)
But it sounds inferior in many respects. Lasers require line of sight, which is obviously a problem. We really ought to be investing in quality infrastructure.
Are there actually people who are anti-nuclear and ok with coal? I don't know any.
You'd better hope the supersonic whoosh doesn't set off the alarm.
Install a filter on your computer so you never see the harassment online. Problem solved.
That's too inefficient to be useful. There are thermodynamic limits on what you can do with heat.
So, is fire alive? A key qualification has to be heredity, otherwise you can't rule out simple chemical reactions like fire.
Have we yet built a self-replicating robot? (without cheating)
"Hey underling, do you work for a moron?"
Obviously, when individuals start paying Big Data to work for them.
