As much as I agree with you, I don't see this happening any time soon. See, Baidu and Yandex already existed for years before reaching the size they're today.

As much as I agree with you, I don't see this happening any time soon. See, Baidu and Yandex already existed for years before reaching the size they're today. Brazil had it's internally developed search engines before (Cadê, TodoBR, Aonde). Some of them even ranked higher than Google in the early 2000s. However, with time they got out of business or were bought by Yahoo or Google itself. And when you think about it, those business (Yandex, Baidu) now offer more than just search - Yandex offers email, maps and more; Baidu has Cloud Storage, Browser and even hosts a Wikipedia-like website - or have some degree of government ties at their countries - Google being banned from China; Yandex reportedly handled information for FSB. You need to have all those advantages to replicate the success case of Yandex and Baidu. And there's one of them - time on market - that you can't buy.
