I wonder if they solved all the multi thread speculative execution vulnerabilities Intel has been struggling with, or if this just makes it worse. That is a scary prospect.

AMD's SMT is different from Intel's HT - only HT is known to have vulnerabilities related to speculative execution. Your worries here are unfounded.

The x86 architecture has been hitting something of a wall lately but AMD looks like it could be set to inject it with a fresh breath of life. According to the rumor mill, the company has finalized the Zen 3 design and it introduces a new SMT4 feature that will allow each core to execute four threads simultaneously.
