Will more African "old monies" invest in tech-startups

I once had the opportunity to pitch my technology startup idea to a Nigerian millionaire; I used all the fine words and financial terminologies possible to convince him to drop some seed funding for me to start implementation and prototyping.After my 20 minutes presentation, to which he listened with rapt attention, baba asked me and I quote," how much can you make monthly, and when can you start paying me back?. At that moment, I knew that I had been speaking the language of coding and debugging to a man who only understood the language of planting and harvesting.The man is classified as an "old money" who made his wealth from farming, real estate and importation of cars. The 21st-century startups have been finding it hard to get funded by the "old monies" because of the "invest and wait" concept of the modern digital economy.Things are changing, and some "old monies" are already onboarding in the new technology startup space, and we hope to see more in the future. However, I guess the vagueness of tech-ideas to them and the high risk of loosing millions in a startup idea remains the fear of old monies. Old monies are sure that no matter what, when they import cars, they can see what the paid for and they can sell gradually but some tech products are just "lines of codes". I don’t blame the old monies.The question is "how do we get more African old monies to invest more in tech?The question continues...
