Will lake malawi become a salt lake in the next 100,000 to 1000,000 years?

I am just curious because all the salts and minerals don't get out of the lake so the water is becoming harder everyday so please answer my question with a nice long explanation.Will lake malawi become a salt lake in the next 100,000 to 1000,000 years?
it all depends on evaporation and the earth's atmosphere. if there is a lot of rain and its humid the air already has water and it can go to a certain amount which will eventually cause rain. if it is dry and hot then evaporation rates can increases. so the lake can eventually evaporate leaving behind salt deposits in as long as 100,000 years. but it all depends on the earth's atmosphere
