And your assumptions are

1. The inventor will not create a machine that would render the sufuria and mwiko irrelevant

2. The market (those who eat Ugali) are too poor to make the purchase. Pragmatists play catchup all the time. As one tell me you still use firewood in your house and I will believe your theory.

Wrong assumptions...maybe for you after a few shillings and cents, you don't pertake of Ugali anymore because your taste has changed and you indulge more in gourmet food, but just look around,how many hotels have incorporated ugali in their menu? I know many wazuans who cant go a day without ugali and I can also say they are not poor in any way. You know...even b4 the sufuria, there were clay pots, and b4 plates and spoons there were calabashes and guards.

As for the digital camera...where is Kodak today? Do you know Kodak made the first digital camera in 1975 but they dropped it because it threatened their film developing business...

Yes. Ugali machine proponents, when can we expect to see your machine in the market?

I have been developing (in my thoughts) the ugali making machine for much of my high school and campus life...I came up with very complicated contraption that might make the machine very difficult to maintain.

Well its easier to make a Ugali machine that can make Ugali with a Vickers Hardness test value equal to that of Ugali made in Zambia,Nyassaland and ZIM.
This could be done easily using a machine like the concrete mixer or mixing the right amount of ingredient and letting them cook in some solar basket.

However, to make a Ugali machine with Vicker's harness value equals to the standard of Ugali cooked in Western Kenya and Luo-Nyanza, you will need a more intelligent machine.
The machine should also be very robust and have inbuilt temperature sensors on the cooking stick to self-time the right time to add flour.
This heavy duty machine should also have olfactory sensors to detect the "smell" the ugali burning towards the end of the cooking...

All is not lost however since I am still imaging to tome up with options which can give the same Vicker's hardness number but with less complications.
