It's a complicated question. Ofc the globalist kike's transhumanism vision for the world is obviously evil and should be shunned. OTOH, there are literally millions and millions of disenfranchised men--many of whom are good men--who have been left out in the cold by the evil results of (((feminism))) (also largely directed by these same globohomo kikes ofc). It's those men that /robowaifu/ should be focused on helping imo. For me, that's the gist of the ethical question.
And (just to diverge a bit) the weird idea that some have pushed that a machine+software is somehow 'alive' and therefore deserves 'rights' is ludicrous. These faggy ideas about ZOMG don't raep teh waifubot!111 are just silly. It is a machine people. And while it's ridiculous, the fact that there are people delusional enough to literally believe these ideas, simply because a machine is physically shaped similar to the human form is, quite frankly, disturbing to me.
Anyway, back to your question. Yes, I think it is right to create robowaifus in the same way I think it's right to create automobiles or phones. Ofc there are abuses, but overall the benefits pretty much overwhelmingly outweigh the detriments anon. Helping these millions of men suffering under this modern plague of gynocentrism is well worth dealing with the issues that will arise.
