Learn Finnish: Tekoäly korvannee monta työpaikkaa. - Artificial intelligence is likely to replace many jobs.

This is the potential mood of the verb korvata (to replace). Because korvata is a type 4 verb, its potential mood is built on the consonant stem korvat-. When we attach the potential marker -ne-, the t assimilates to match the following n, turning korvat-ne- into korvanne-.

Why does korvannee end with a double e?

The potential mood follows the same personal ending rules as the regular present tense. The stem is korvanne-, and because the subject tekoäly is third-person singular (it), we lengthen the final vowel. Therefore, korvanne- + e becomes korvannee.

Why is the object monta työpaikkaa in the partitive case?

The word monta is the partitive form of moni (many). Whenever you use monta as a quantifier to mean "many of [a countable noun]", the noun that follows it must also be in the partitive singular. That is why työpaikka becomes työpaikkaa.
