Not at all.
What I'm saying is SSD may be good for kitchen usage, not for
heavy use (and especially big files often fully rewritten, as
in CAD systems).
And this is what you confirm below.

Re-reading the beginning of your §, I'm now asking myself a
terrible question (as the 10K barrier last for long now):
is the 10K a real physical barrier to SSD life, or is it
the same like the 1,000 hours duration for light bulbs.
I know there's a "cage destruction" effect when writing a
SSD cell, nevertheless I wouldn't be surprised that this
barrier's already broken but stays covered (imagine a
technological breakthrough that would allow 1000K writes/cell,
it would be spinning HDz' end right'o and a more than
a significant SSD sales decrease rapidly).
I'm not writing a novel, I know a bit of physics and some
people that are researchers in the branch of new/improved
techniques of substrates masking/doping…
