Not me. Not in this news string. (Although I proposed similar stuff earlier in comp.arch.)

I'm just a fan.


I don't think that what Andy has proposed is necessarily a waste of
hardware, transistors, performance, or money, but it may lead to even
more sloppy programming. I don't worry much about syntax because it
costs little to get the compiler to find the errors. I'm not so sure
things would be better if programmers were counting on the hardware to
catch programming and conceptual errors.

I share this concern.

HardBound and SoftBound would lead to more system interruptions. Instead of a buffer overflow allowing a bad guy to break into your system, they would take the subsystem down. But the webserver would reboot or restart.

There might be fewer bugs overall, however, because more would be caught in testing.

It's a lot like Java and Javascript: the ability to fix bugs easily in production has led to initial code drops often being buggier than in the old days.
