condescending tone.\u00a0 Although the response would be considered tame had it been provided by a human with greater experience, this was not acceptable from an automated system.\u00a0 It spent over a minute consuming energy to reply with an answer that was dismissive and flippant.\u00a0 I didn’t let it go and provided the feedback to the prompt.<\/p>\n<p><a

automated systems is not the same afforded to people.\u00a0 Hand made tools and precise machined tools have never been in the same classification, nor should they.\u00a0 I found that the AI responses to be peppered with personal whims and clever queues that appear to be the purpose of the provider to create a more natural interaction.\u00a0 I also found that the AI responses took longer and contained lengthy complexity, often with content that was beyond the scope of the request.\u00a0 This was a pattern that I observer repeatedly.\u00a0 It reminded me of a discussion about the
