I love your aspirational and positive attitude.
"Other issues you mentioned such as electricity and water are the reason why you will find some of the most innovative people out there. Rather than complain about their inconvenient lack of opportunities, they think outside the box to achieve whatever they want to achieve."
I get it - if you don't have consistent electricity you 'innovate' and I admire that a lot. But I'm sorry - you're going to need consistent electricity to do many things. It's not a 'complaint'.
There's just no way around having basic infrastructure. Also - consider that a nation that cannot get consistent electricity obviously has some deep problems. So it's partly the 'lack of electricity' - but really, it's the 'problems that cause a nation to not be able to have electricity' - those are the real underlying problems.
That said, nowhere in East Africa is going to be making electronics in any capacity any time soon.
You should also consider thy on earth you would want to do that, as it's not really a natural advantage.
I live in Canada - and we don't make many electronics either! Because it's not suited to us.
Does your President/Prime Minister have political control of the Central Bank, and the large National banks, and can he use it to make massive strategic investments in certain technologies and use it for export financing?
Do you have an attractive enough economy that you can lure international investors, and then force them to hand over their IP? Do you have the depth of Engineering talent to take the plans for an advanced European rail system, copy them, make your own train system?
Do you have a malleable a population of professionals willing to work cheap, to be servile to others and say 'yes, yes, yes' no matter what, work 7 days a week and get it done no matter what? Those are strong words, but that's China for the last 30 years, working with them, they always say 'Yes', it's always cheap, and they move extremely quickly. The results are something else to talk about, but they have a very specific kind of attitude towards work, that for better or worse, works for them. They have a strong sense of nationalist vigour like right out of the 1950's.
So if you can't have enough foundational sophisticate to do electricity, let alone those things, then as you say, with an innovative attitude you can just do something other than electronics.
Much higher value and branded goods along the lines of what Africa is doing already, i.e. going 'up market' at least on some things. Exotic produce, processed, textiles, definitely tourism and of course agriculture, probably specialised.
Think of the economy like a pyramid. If you want to build higher, you have to have a wider, and more solid base. It would be a much higher ROI for any nation to establish competent civics (ie 'base') that it would to try to develop advanced foundries.
Last note: the elite in Africa is a problem, moreover, there is no 'professional class' of owners, artisans ie tradition of highly competent people doing complicated, industrious things handing down from generation to generation. Surely there was some of this, it's just adaptable to our current version of globalism.
China has had an established bureaucracy for thousands of years. So has Europe. Africa and 'mostly' South America have not, and that is the 'social pyramid' (of competency, not just power) which is necessary as well. Though there are some obvious things about that people find unfair, it's just as unavoidable.
