I think the things happening behind the scene will gradually become meaningless and just token efforts paying lip service to the issues. It's not movements or initiatives that effect change, it's individuals. Sadly, it often means those individuals have to devote the rest of their lives to their cause (change never happens fast once it's ingrained).
Maybe, or maybe not ... we have to wait and see.
But its not charity that is going to make change ... black people have to want to do it and LH has given a great example to be followed. That is the individual making change that you referenced - even if you might not have meant it that way.... I watched F1 for years and never saw a black face - and never even dreamed of a black driver ... and then one came along ... and look who it was!
Others will now know that it is possible - and it will be up to them whether they want to do it or not. To be engineers, fabricators, mechanics, strategists, marshalls or drivers.... f1 is there if you want it.
But ultimately, its down to individual black people to decide if they want to do it - and then do what is necessary to get there. The charity is helpful, and welcomed - but dont think that is going to be the biggest factor.
Every field that you see black people in today where they are doing well in it, at some point in the past they were literally barred from being a part of it (I am talking about in the major western countries now) ... and then some decided that they wanted to be a part of it ... so they did it - and it wasnt easy - but they did it anyway ... because they wanted to do it. Not because someone set up a commission or whatever..... as the Jeffersons theme song said "it took a whole of t-trying, just to get up that hill.." ... a lot of "trying", not a lot of "help". (... but dont get me wrong, I am not against "help" - its not a bad thing, just get the order of priority right).
LH has given a great example ... we now have to see how many will want to follow it... in different aspects of F1 and motorsport.... that is how change really works.
