You obviously don’t know the difference between a torch, and a cauldron. Also, it pays to note that the swimming venue in Rio was built as a temporary venue, and not a permanent one. It is not as if it was built as a permanent venue that has been abandoned. Rio has simply failed to take it completely down after the games. In the end, none of the negatives in the video are the fault of the games themselves, but of the host cities.
Then there is the example of London 2012, whereby the village, the Aquatics Center, the Olympic Stadium, and the Copper Box, are all in use to this day, and the whole of Queen Elizabeth Olympic Park, is a beautiful legacy of the games. Once again, it’s not the games, it’s the host city.
Your view on Atlanta is very flawed. Atlanta is the one place that at least reused or demolished old buildings. The one note moving the torch by the old Turner Field is very weak and that was only the first out of two points. Even the second point is weak. There may be a plan to build a mixed-use center on the old tennis complex. Only time will tell if it goes through but your online two points are extremely weak and holds no water. Because of this, this entire video can not be viewed as credible.
When a Country bids for the Olympics a condition should be that there are plans for the venues and their aftercare and use for the community they were built in. Maybe Social and Sporting initiatives that will help future sport stars and local children and communites get involved in sport. This would prevent this happening from Tokyyo and beyond
