@vbabka @ljs I see the problem! In Korea, it's considered inappropriate to sign using red ink. "It is a common Korean superstition that if someone’s name is written in red, then death or bad luck will come to that person very soon." Should have been blue or black :'( https://gwangjunewsgic.com/arts-culture/korean-myths/behind-the-myth-the-red-pen/

@mathieu@fosstodon.org How will it succeed (in an economically viable sense) if the tech isn't great? The bubble will burst at some point anyway if the tech can't back up the expectations. I feel like people have stopped thinking rationally (cuz I don't see any clue or potential that the machine is going to take over, at least for now) and are just going wild & pouring an insane amount of money into it... They'll have to face the consequences eventually, but what worries me is that it might affect the people around me (who aren't doing AI stuff). +1 for questioning my own sanity.... you're not alone! hehe

@mathieu@fosstodon.org

While I've been thinking rationally about this, I've a feeling a large part of our peers haven't

... that's truely concerning, yeah. It'll take some time (hopefully until it's too late) for people to realize.

My take is that the tech is "good enough" (see latest claude etc)

Yeah, it's quite good! the only problem is...

that people will keep hyping it just enough that it will justify printing more money for it.

...that it doesn't seem like the industry is making a reasonable investment or carefully applying the tech to reality.

In the long run will we see the harsh reality of this (hard to fix bugs etc)? Sure! Will it be too late ? Pretty sure that's also a yes.

Sadly yes :(

Anyway sorry my reasoning is a bit all over the place, it's just confusing times

Don't worry. It's confusing time for everybody...

@mathieu@fosstodon.org seems like it's just human nature to feel enormous excitement and worry at the same time whenever a fancy new tech comes out (only to realize later it wasn't as good or bad as expected) /me stares at his stock account and wondering when to pull out (but yeah it's not just about the stock market)

@Aissen@social.treehouse.systems @axboe@fosstodon.org @gregkh@social.kernel.org @ljs@mastodonapp.uk @vbabka@mastodon.social bittersweet because people report bugs on features they don't use rather than fixing them and stepping up to help?
