The Healthusiasm Podcast

The episode contains several substantive ideas - shadow AI, the role of physicians in an AI-dominated future, the 'two speeds' of healthcare vs. technology adoption, and the distinction between health (machine) and care (human) - but these are interspersed with extensive throat-clearing, anecdotes about HLTH conference logistics, and conversational meandering that dilutes density. The guest does surface interesting frameworks but much airtime is spent on tangential discussions.

“Technology's achieved escape velocity, as in healthcare will never capture it.”

“Care is human, health is machine.”

The core tension between regulation/safety and innovation pace is not new; the 'two speeds' metaphor is useful but not particularly novel. The idea of AI changing the physician role is well-trodden ground. However, the framing around shadow AI adoption in healthcare and the specific example of ambient voice transcription adoption data (with the June policy shift causing perception change) offers some fresh empirical observation. The 'energy between humans' argument is more philosophical than original.

“People using WhatsApp to send some page director to somebody else.”

“The ambient voice technology... at the start it was making sense of it and discussion about like, you know, it's great, and other people saying it's terrible. It's become kind of much more nuanced over the year.”

Dr. Keith Grimes is a practicing medical doctor turned digital health safety officer with real domain experience (worked at Babylon, runs Curistica, moderates the 800-person 'AI and the NHS' WhatsApp group). He has genuine operational context in AI deployment in healthcare and regulatory navigation. However, he is not a household name in the space and the episode does not draw out deep operational war stories or specific case studies that would elevate him further; much of his credibility comes from his thoughtful framing rather than battle-tested examples.

“I'm a doctor by background, a general practitioner in the UK, but I was always a real geek and techie person. my company, Curistica, is a company that provides safety services, you know, clinical risk management and safety services.”

“I'm one of the moderators and admins in that group. It has about, it has, as of this morning, 796 members.”

The episode cites the June 9th policy letter from Alec Price Forbes on scribes and references the AI and NHS WhatsApp group with 796 members, which are specific data points. However, the claims about 230 million health questions per week on ChatGPT and 1-in-5 Microsoft Copilot users asking health questions are cited without source attribution, and most strategic claims lack concrete examples or metrics. The discussion of the role of physicians post-AI is largely abstract and speculative without grounding in actual deployment outcomes.

“On June the 9th last year, so just before health last year, put out a letter to all the practices in England.”

“It has about, it has, as of this morning, 796 members.”

The host asks reasonable opening questions but frequently allows the conversation to drift into anecdotal territory (HLTH conference details, rugby vs. football, personal stories) without sharp redirects or probing follow-ups on key claims. When Dr. Grimes makes substantial points - e.g., about the role of human presence in care, or the shift in ambient voice adoption - the host does not press for specifics or evidence. The conversation is collegial but lacks the tension or intellectual rigor that would deepen insight. Some softball moments go unchallenged.

“Tell me, you were there, right? So how was health?”

“Yeah, well, the I know, I mean, and it's and it's probably the most valuable thing to do right now.”
