Technically there is nothing wrong with this system. It will be financed privately and also its footprint will be rather small.^^ Behaving like a 5 year old who has seen his friends shiny new toy and goes on a hunger strike. This cable car system, the subject of the thread, is one among very many solutions that will benefit your cities.
Instead of throwing tantrums, swearing never to invest in the flower industry—like Azedu did—& rubbishing your country because Ethiopia has a shiny new light rail system, propose creative solutions and play an active role in making your situation better.
Very soon, your big railway project will be ready, don't cry.
My problem with this system is that it will allow politicians to delay a 'real' solution for Public Transport in Nairobi. It is another sham like the half-hearted attempt at Nairobi Commuter Rail or the ever proposed BRT.
