IMHO Ordinals are a blessing. They teach us what it means to be a permission-less network. They prepare the network for worse. Without them a bigger attack could come as a nasty surprise. Ordinals are part of growing up. I suspect more Ordinal-like attempts will be made, and why not? It's a permission-less network. Miner are free to exclude them. 

 YHO is not fact. Thankfully. 

 I think the Chinese miner-ban was also a blessing. Imagine not truly knowing what a substantial miner-ban would mean for bitcoin. Same with the silly ordinals. I think they will not survive and only make the network stronger by having been part of the evolution of Bitcoin.
