Yea I've definitely had situations where I've been challenged in this way (in which I definitely was having a voice-only conversation that seemed to be targeted after the fact). It can be vexing.
It was mentioned elsewhere in this thread, but this is where Baader Meinhof may apply. I don't how many times I've seen a targeted ad that was a "miss" in terms of recency bias. But I absolutely remember every time there was a "hit".
Both situations were targeted based on my digital behavior, but they're playing the volume shooter game. Taking as many shots as possible hoping eventually they score. This could be true in your case. The fact that you and your wife were having a recurring conversation about stem cell research, diabetes, etc. suggests that its likely that this is in your digital fingerprint at least once in the past (recent or otherwise).
Something I try to do now, when I'm being mindful about it, is note how often I see ads that are definitely in my interest bucket but are completely uncorrelated with any recent conversations I've had. That helps at least establish an anecdotal ratio of hits-to-misses that makes the Orwellian/dystopian much less reasonable on balance.
