Bold statement. But: 1) nothing is the new IE - IE<9 was the worst for frontenend web dev. The web would be another (better) web, if there was no IE. An IE is a clumsy browser with a shitty update cycle, with huge market share. So: Safari is right now more IE than any other browser.

2) In the article is nothing that proves your statement, no links and benchmarks or tests.

3) I really need a new watch.
