Q. Can one use a computer that follows Alexa or Siri type of vocal instructions do melachot (prohibited works) on Shabbat, if it is programmed to only randomly follow up instructions 50% of the time? Since this scenario is definitely not a Pesik Reisha or a certainty that the Melacha will be done and is also done with a Shinui (in an unusual way), is it permitted?
Horav Shlomo Miller's Shlit'a opinion is that it is not since it is a 'Dovor Hamiskaven' or an act done with intention, and that is not permitted even when not a Pesik Reisha.
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit'a
