Sure, suppose the ICO craze spreads even further. It carries the ETH price to a thousand bucks. Or several. Whatever. Something extreme.
What exactly have shifted? Will your BTC be worthless? No. Will the companies and services go away? No. Or consider the other way around, there is a new DAO and now it's worth fifty cents. BTC doesn't care.
For a something supposedly declared obsolete, altcoin shills sure have a fixation with Bitcoin...
That's a little like rabbis asking what's shifted with the whole Christianity thing. I'm not sure if they will be the new religion, but they're proselytising at a faster pace currently, and that's bad news for those of us who seek power above belief.
We are comparing a method of knowledge (science) to a system of belief (faith), which is not known for revising itself based on new evidence. Even when it does, the wrongs are blamed on human interpretation. Science is all about improving ideas to get closer to the truth, and, in some cases, completely throwing out theories that have been proven wrong. Furthermore, the claims of religion are virtually all unfalsifiable, thus cannot be proven wrong. Therefore, comparing religion and science on the basis of falsifiability is a faulty comparison.
