there there are antisocial surprises, like YC's 'login' required after writing a post - which led me to go log into another machine, check my list, then come back here and login. Looming is the question whether a login failure would've erased what I wrote. There are of course fantasticaly more egregious UX gaffes.. imagining now [cp] and [ls] buttons .. perhaps better than 'intelligent' locator select/copy/paste madddenlingly split between kb keys and screen touches, highlighting not exactly what precisely you specify, instead crazily jumpping the selection about phrenically, while necessity of scrolling offscreen up and down further complicates - often 'select all' means 'select only whats onscreen' <surprise later, only after a paste> micro displays, big thumbs, filly 5/8ths of my present Android screen obscured by an on-screen keyboaard, even though I'm typing on a BT kb. As you might infer from this rambling paragraph I'm an OOtB ADHD wannabe-Dev type, enough at least to have heard about 'DNRY' which in sum, I'd say I hope Ai somehow obliterates <after the fashion of *nix apt's, perhaps?> with 'you can you it anyway you like - there are a dozen ways to do anything, and they all work all the time - modulo of course in reality that anti-DNRY paridigm taken beyond the UI foments chaos and confusion.
