Depends on how your gear was made. There are simple measures against
this. Especially with the high performance/resilience capacitors
available today.

This only says something about *your* gear, not about equipment in
general. Suggest you browse around the manley or avalon catalog. But
then those things cost, for example, 20000 usd upwards per channel,
and are used by mastering engineers; your mixing/project studio
doesn't need or have this. So why argue nobody needs something by
proving that *you* don't need it?

I'm sure you've done a lot of statistics here, sarcastically speaking.
Again you are trying to disprove in general a statement that can be
true or false from instance to instance by showing single examples.
Bear in mind that what you have experienced is not end-all be-all and
people have different techniques of doing things. The existence of
fully digital signal paths does not invalidate previous approaches;
sometimes it can just enforce them. But to answer your argument: no,
DAWs are not always used for mixing and people will use Protools with
Euphonix to automate their analogue mixers with motorized faders.
There is a lot of talk about analogue summation. Protools is then used
just as a hard disk recorder and recall happens through the analogue
hardware, in which situation again it is important not to have a lot
of temperature dependency.

So *you* don't care about it, and are therefore using this to prove
that *nobody* cares about it? Do you see the problem here? A sort of
egoistic view of the world, and this - according to basic predicate
logic - disallows you from proving your point. The arguments and
experience you have provided are completely and utterly subjective and
biased.
