Thoughts on software-defined silicon

I feel like the natural consequence of "let's put software in everything" is that everything will be full of bugs and security problems.

I'm not really a fan of rentier models, but I think the technical problems that will come are enough to make this a bad idea.

Sure there are examples of doing this in the mainframe era, but mainframes were not living in our modern world of security attacks. Additionally, the pricetags and dev cycles of those systems meant that a lot more attention was given to the implementations at least in an attention / complexity ratio sense.
