Given that there are algorithms that can solve our

they are mostly preventing the lazy and those that don't have enough
knowledge to use those algorithims. I would guess that text on an image
without any blurring or manipulation would be just as hard for those
sorts of people to break. (Obviously that's a rather large guess). As a
compromise maybe we should have straight text in image captchas.
A simple thing that could be done is to introduce localized captchas on
non-Latin wikis (just remember that not everyone has the appropriate
keyboard). This would mean that new captcha-cracking algorithms would
need to be developed for each script, and if the wikis are small,
spammers would not bother.
Any developer interested in Wikimedia wiki CAPTCHAs should look at
<https://www.mediawiki.org/wiki/Requests_for_comment/CAPTCHA>. There's
some low-hanging bug fruit there.
