I have my doubts and I'll definitely be sitting on the sidelines for this one, but I think the big thing going for blazor would be the apparent 'difficulty' in reverse engineering the bytecode, which I can see many a decision maker wanting to protect their Intellectual Property in this fashion. Although this has an equal and opposite reaction, which would be the difficulty of debugging, but this is based on the traditionally way of debugging using the browsers' dev tools. Perhaps this will be a total moot point in the near future.
Regarding client side speed tests, and please forgive my ignorance on this matter, but does Web Assembly have access to the clients' multicore processors, if so this would be another plus as my understanding of JS, <ignorance> is although you can thread using 'workers', they are running on one core.</ignorance>
