Well, actually I don't think the <blink> tag works in any modern browser anymore. Just like <marquee>, it was never part of any standard, it was overused back in the day to the point where it became super annoying, not to mention the accessibility nightmare it was. So no, blinking text on websites is not something we should bring back.
And regardless, nowadays HTML should only be used to describe the structure of a page, not how it looks or behaves, and that's why many of the old tags are deprecated and support slowly dropped. Nowadays different "languages" are used to set how the page should look and operate. Using those it's ofc possible to make text (or any element on the page) blink, there just isn't a single HTML tag for it anymore.
