It's 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... :) > > Patience is the key. Seeing patches refreshed within a day is killing me. 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... > > > only with AI that they've been able to skip that step, to everyone's > > detriment. 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). > > > > There are some patchsets in my inbox that I instinctively just skipped, > > because they were huge new patchsets from new AIs (not people, really), > > only to watch in dismay as they burned up other people's time in > > review attempts. 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 :) > > > > thanks, > > -- > > John Hubbard > > > Best Regards, > Yan, Zi -- Cheers, Lorenzo
