I have read the article from which the list is derived and at least two things are apparent.
First and foremost, we should separate the stupid effects that are there for cinematic and TV effect from those that just might be possible with some being more possible than others.
My second point there is not one practical, get your hands dirty, engineer objecting to the things that are left, which leaves just scientists that are objecting.
Now the question becomes what are those scientists objecting too? Are they just repeating dogma learned from others that were just repeating dogma learned from others etc.? How do they know what they are objecting too won't work - have they tried or even thought about it without their dogma getting in the way?
In the past there were a lot of ideas about how the universe worked. Eventually Newton put together a working model - it wasn't complete but it could be used and was proved to be accurate enough and everyone said this is the bees knees. Then along came Einstein, he added to the work of Newton but he had a blind spot, at a young age he had decided that the speed of light was constant despite the Mickelson Moreley experiment showing otherwise. Now everyone said the work of Einstein was the bees knees.
Newton didn't have the complete answer and you can be sure that Einstein didn't. Most scientists still see the work of Einstein as the bees knees and woe betide anyone that even hints there might be imperfections in it.
So we end up with schools and universities teaching the there is nothing beyond Einstein and most scientists accept that as fact. Just witness the plethora of weird and wonderful particles posited to get round the Einstein restrictions and keep the established scientific community happy.
As far as I can see the scientific community needs to accept that the work of Einstein, like the work of Newton, is just a step along the way and they need to stop navel gazing and start looking outward, stop saying it can't work and saying how could we make it work.
I was born at the very tail end of the age when people tried things for the sake of trying - some things worked, others didn't. If it didn't you tried again but in a slightly different way. I remember telling my grandfather that the teacher had said that something wouldn't work - I forget exactly what - and his reply, have you tried? This is the attitude we need to get back to today, the scientists need to try things rather than saying, 'the theory says no'.
Rant over and as an aside we see the same in SF today with most books of the last few years being inward looking, doom and gloom rather than outward looking and hopeful.
