On the security side, zkVMs are highly complex software projects still riddled with bugs. On the performance side, proving correct execution of a program can be hundreds of thousands of times slower than running it natively, making real-world deployment for most applications untenable right now.

Despite these realities, much of the blockchain industry portrays zkVMs as ready for immediate deployment.

Found this interesting because I've been reading that 'zk is the endgame' and many people on Twitter suggested that this zk revolution is just around the corner. The author disagrees and says we are still a few years from thaf level of zkVMs.
