I should know, I did the Eudyptula challenge then stuff in the staging drivers
then I wrote a book etc. you know the usual stuff :P

It took years because it's you know a lot. And I still don't really understand
anything (therein lies the zen state of knowing enough to know ones own
incredible ignorance... :)

Tell me about it :) the workslopload since the slopularity (circa
late 2025) is slopcrazy.

We so need some kind of a support group... maybe at LPC? :) I nominate the
pub as the venue for this...

Yeah. And also there are a number of people who, bless them, simply could
never get to the point of being able to contribute.

I really do think talent is a factor (I know for some this is a
controversial position) as well as bloody-mindedness, a certain way of
thinking about perhaps some masochism thrown in there somewhere ;)

I think only a small % of a small % have what it takes.

In the past those who could not, would not, even if they tried a little
first.

Now those who can not, do, but do so with absolutely no understanding or
sane guardrails (Dunning Kruger comes into play here also).

I fear doing so in case things end up getting merged mistakenly.

But I am certainly a lot more quickly dismissive of this crap than I used
to be, simply because I only have finite time and an infinite amount of
work to do :)
