Do we have more hardware isolation? There was a pretty strong argument against microkernels - a driver running in userspace can still bork the whole machine if the hardware being controlled can write to memory at arbitrary addresses.

we have more hardware isolation.

they are seldom implemented correctly on firmware/mainboard level.

Yes, there's IOMMUs.

On the other hand, datacenters have become so large that a 1% performance improvement can amount to millions of dollars in hardware and energy savings, so the extra cost of a microkernel might not be very welcome outside consumer devices.

We did not yet have a big publicized hack of whole cloud infrastructure causing massive economic harm. When that happens (the buggy PC/Linux architecture running the world is ripe), more secure architectures will become commercially interesting despite the 1% performance penalty.

Hardly of value with kubernetes everywhere running on top of type 1 hypervisors.

Microkernels have won, even if monolitich kernel advocates haven't yet got the message.
