Some of my worst courses have been Field theorist teaching electromagnetism.
Perhaps you are confusing the first and the second clause of fifth amendment?
Yes, but there are level of beliefs that can be assigned to arbitrary hypothesis. Consider the fact(s) that
1) the scientific consensus agrees that most human being are almost equivalent in skills and intelligence to form decent social structures
2) Africa has a billion plus human being, the scale at which laws of large number dictates that their overall behavior should be close to human mean.
3) there have been advanced cultures in Africa in past, as recent as just before European colonization.
Keeping that in mind, reasonable people would agree that Africans are not inferior merely due to continent they are born upon. Is this the scientific level of proof that matches the 5 sigma precision coming out of LHC? No. But it is reasonable to expect so, and no proper scientific resources are being devoted to this micro-study, after most of Science has already has rejected idea that one large group of humans could be statistically inferior to other large group.
As a side note, you might not have realized it, but similar arguments have been used (and are still being used) by people who want to raise a rhetorical question, like how do you know that evolution explains x,y,z fact? More often than not, these people do not have intention of genuine questioning but rather want to show that ignorance of one detailed thought experiment is enough to discredit entire field of scientific evidence. It is thus not surprising that people would think that you belong to one of that group.
This is false. The biggest government benefit that someone employed at Walmart gets is the EITC, the _Earned_ income tax credit. For a person earning 20k with family of 4, the EITC would be near 5k, or a quarter of the salary. If the person was not working, the government (usually) does not pays anyone 25k for non working. Moreover, without the $5k EITC, it would not be economically feasible for this person to work at Walmart, and Walmart would have to simply pay its worker more to at least find people who can eat enough. The government is absolutely subsidizing Walmart in tune of $3-4k per worker.
Unconstrained optimization is NP-hard problem, and quantum approaches won't change that. However, D-wave hopes they are faster in solving optimizations than classical solvers, something they haven't demonstrated yet. The fact whether D-wave is actually a Quantum machine is interesting to Computer Scientists and Physicist who care about accuracy of commercial hype, and also to D-wave's future customers.
