So you argue we discriminate based on who/what wrote the code, instead of what's in it?

Let's take this to a different domain, self driving cars. Would you equally argue for human driving? I'm pretty sure over time it will become clear to everyone that machines will be able to outperform humans consistently at this task, to the degree that human driving will become illegal. But for now the press likes to focus on any failure of machine driving, taking for granted human drivers are the largest or second largest cause of premature death in many countries.

Coding (in many ways, but not all) is a more open ended and versatile task than driving, so it's natural that current iterations seem untrustworthy, but ignoring the trajectory is erring on conservatism, and doesn't seem to me to be grounded in any sound reasoning.
