If you post logically , then I can argue .
But stuff. like glass surface ?
Will it happen in 50 years?
I have not posted anything that is illogical. You have no idea about technology, nor tennis, so why post here of all places?
Is the surface not dangerous? I haven't seen the video, since it's not working. But glass would indicate very slippery to me and potentially dangerous.
Though from a viewing perspective and if the accuracy of the calls is good, then I'm all up for it.
I thought so at first as well, but no, it is not slippery in any way, as long as the proper humidity is maintained. It surely cannot be used in outdoor conditions yet, but it can be developed in time, with either a new layer that can protect against loss of adherence or a coating to the glass that only affects that laser effect in a minor way.
