I wonder if Prof Hirano would have bothered to come to the UK at all if the Charlie Gard case hadn't had world wide publicity?
Not entirely sure that is fair.
What I am more interested in is why he changed his mind about the potential effectiveness of the treatment from April to July. In the April judgement Dr I (whom we presume to be Hirano) said:
'Seeing the documents this morning has been very helpful. I can understand the opinions that he is so severely affected by encephalopathy that any attempt at therapy would be futile. I agree that it is very unlikely that he will improve with that therapy. It is unlikely.'
Then suddenly in July he changed his mind - having now offered to provide the treatment I don't think he could reasonably have refused to visit Charlie in the UK.
Worth noting too that Hirano was involved in providing expert opinion way back at the beginning of the year, long before the case had generated any meaningful publicity.
