No response to https://forums.theregister.com/forum/all/2026/04/22/anthropic_mythos_hype_nothingburger/#c_5266893 after five days (and no correction to the article); that's disappointing.
I'll respectfully request a correction.
I refrained from sending an email, because @bigsneakyduck had already done so (mentioned in Reddit: "… I've tried reducing this to the bare minimum and sent an email to corrections at theregister dot com.").
