This should not (so much) be compared with Fully Homomorphic Encryption (FHE) but with a Trusted Execution Environment (TEE). It is a very elegant and minimal way to implement TEEs, but suffers from the same drawbacks: a data owner has to trust the service provider to publish the public keys of actual properly constructed Mojo-V hardware rather than arbitrary public keys or public keys of maliciously constructed Mojo-V hardware.

After skimming through the documentation this seems like a nice solution, but I'm not sure if this is a problem we want to solve.
Consumers are finding out the issue with cloud computing when their heating system can't turn on because Cloudflare is down. A cheaper and more reliable solution is still on-premises computing.
Large social network and content platforms don't have any incentive to keep your data safe because they want to monitor and own everything.
Maybe this is for something like a government running a public service?

Was it really wise to name this Mojo when Chris Lattner, former Head 9f Engineering at SiFive also called his well funded programming language Mojo?

This could be:
Great for security - Being able to safely compute secrets is a very difficult problem.
Fucking awful for security - More OEM secret controls and "analytics" that devolve into backdoors after someone yet again post keys online.
