It would be cool if most PCs had a general purpose FPGA that could be repurposed by the operating system. For example you could use it as a security processor like a TPM or as a bootrom, or you could repurpose it for DSP or something. It just seems like this would be better in terms of firmware/security/bootloading because you would be more able to fix it if an exploit gets discovered, and it would be leaner because different operating systems can implement their own stuff (for example linux might not want pluton in-chip security, windows might not want coreboot or linux-based boot, bare metal applications can have much simpler boot).
