Reality check.
Analog is fine but it is a choice. both have pro's and cons. The Hubble is not running on analog film. Digital is essential in most every probe we send today, and Mars is a good example. the highest resolution GPS mapping that is emerging is now is digital. 100 plus digital backs have been around for some time now for medium format. Static you speak of may be mostly in your thinking.
I am guessing you prefer vinyl and thats OK ... a personal choice again and arguably better than digital... resurgence, nostalgia and those who are most connected with old technology like film, can create very strong opinions that are not necessarily true.

You guess wrong: I prefer CDs. But don't take that as a blanket endoresement of
unrestircted digital sampling.
I prefer analog guitar effects pedals. Why? Because sampling once at 44.1 kHz sound fine,
but sampling
repeatedly -- converting back and forth from analog to digital to
analog to digital... -- degrades the signal very much.
So its not a matter of "sampling is good" or "sampling is bad". It's all in how a particular
industry uses a particular technology. That's very much the case with digital cameras.
(But some technologies are bad: e,g. asbestos, thalidomide, ActiveX, cigarettes,
MS Windows, electronic voting machines, radium water patent medicines, dirigibles,
"the Cloud", and Roman dinner plates made of lead.)
The first NRO spy satillites did use film -- very sucessfully. So did major astronomical
observatories. The Hubble uses a large format
array of digitial sensors -- something
you cannot buy from Sony, Nikon, Canon, Olympus, etc. So an 8" x 10" film camera is
closer in capability to the Hubble camera than any digitial camera you can buy.
To use any technology successfully, one has to understand it -- it's strengths and it's
limitations. Belief is no substitute for knowledge--and the public can all be wrong
(as we saw with all those "NINJA" mortgages that went into default in 2007).
Also,
one has to be able to control one use of the technology--not some giant
corporation like Microsoft, Amazon, Google, or Sony. If you allow yourself to become
locked-in or dependent, you
will be exploited. Officers of public companies have a duty
to their stockhoders to maximize earnings--if they can legally squeeze another buck from
their customers, they have no choice but to do it.
The naive and trusting will be victimized, as will those who use technologies they do
not understand. Their privacy, security and even their cherished images may vanish.
