I never said that they were in Africa when they invented it did I though? I said black people. And the colonial era bullshit I already explained but you clearly don’t understand what happens when there is a power struggle in a nation.
I did, look at my other comment. The Colonial era wasn’t cause other nations took responsibility to help them, it was to exploit those nations. Now that it’s over they left massive power struggles which then turned those nations into war torn nations and even when those wars ended they still had issues such as poverty and disease which they just didn’t and still don’t have the resources to deal with.
Yes, colonization brought infrastructure but you can’t possibly think it was amazing for the people of those nations. And I’ll name a few. Traffic light, Electric microphone, gas mask, hair brush, automatic elevator doors, the home security system, ironing board, and the automatic gear shift and that’s just a few.
