Explainability, the capability of an artificial intelligence system (AIS) to explain its outcomes in a manner that is comprehensible to human beings at an acceptable level, has been deemed essential for critical sectors, such as healthcare. Is it really the case? In this perspective, we consider two extreme cases, ``Oracle'' (without explainability) versus ``AI Colleague'' (with explainability) for a thorough analysis. We discuss how the level of automation and explainability of AIS can affect the determination of liability among the medical practitioner/facility and manufacturer of AIS. We argue that explainability plays a crucial role in setting a responsibility framework in healthcare, from a legal standpoint, to shape the behavior of all involved parties and mitigate the risk of potential defensive medicine practices.

Computers were once seen as more or less infallible machines that simply processed discrete inputs into discrete outputs, whose calculations were never wrong. If a problem ever arose in a calculation or business process, it was definitionally caused by human error, not the computer. But as machines encroach on ever-more humanlike tasks that go beyond basic number crunching and enter the realm of discernment and decision-making via artificial intelligence (AI), the business world is developing a new understanding of what it means to trust machines. The degree to which businesses and workers learn to trust their AI "colleagues" could play an important role in their business success. Most organizations today say they're data-driven.

AI have entered into a partnership to provide TOPdesk users with expanded IT support through cognitive Artificial Intelligence (AI) by using Amelia, IPsoft's industry-leading digital AI colleague, as a digital IT service desk employee. Amelia will automate routine IT service desk functions to deliver efficient and more timely support services to TOPdesk users, freeing up time for support employees to focus on more critical tasks. AI solution is offered as a service and integrated with TOPdesk's service management software, using Amelia's conversational interface -- in natural language -- as an interactive front-end for users. AI will support this partnership by working together with participating customers to seamlessly integrate Amelia's cognitive AI abilities with their existing TOPdesk deployments. "Amelia is rated as the most intelligent virtual agent by Everest Group and through her unique programming and algorithms, Amelia utilizes each of the human brain s eight core cognitive skills to deliver unparalleled capabilities, surpassing mere chatbots in every way. We look forward to being able to offer Amelia capabilities to TOPdesk users," said Ramon van Leeuwen, CCO at TOPdesk.
