It's entertaining to hypothesise what the continental configurations will look like in 200 million years but what these projections show is a possible snapshot in time over a long complicated process and assume too much.

There's no guarantee that the continents are going to continue their current rate or direction of movement. Evidence from the past, eg the Variscan Orogeny, shows that there were several apparent changes of direction when Gondwanaland moved northwards with bits breaking off and ending up in unexpected places. If we had computer projections at the time looking forwards 200my, we in the UK would probably end up attached to Greenland as the Atlantic didn't exist in late Carboniferous times.

It's great to speculate though Smiling face

Personally I don't intend to lose any sleep over it, one way or another.  I suspect it won't have a great deal of affect on my life!!!!
