I read Soddy's Nobel speech, and it is remarkable that the folks back then developed wet chemistry techniques to resolve isotopes and be able to isolate enough to weigh accurately on the balances of the time. The existence of isotopes was later corroborated by the development of mass spectrometry.
Whoops, 'beta decay converts protons into neutrons and vice-versa' Errr... In the historical context and with the elements being discussed beta decay converts neutrons into protons. There are a few artificial radio-isotopes which decay by positron emission, which really does convert protons into neutrons. Since the majority of beta-decays convert neutrons into protons it's better to say 'beta decay converts neutrons into protons and vice-versa'
You're missing the point of the sentence I think. Beta plus decay and beta minus decay are both forms of beta decay, and both were not known to be conversions of protons to neutrons and vice versa at the time. Nothing more. The sentence has no contextual connection to the rest of the video, other than serving as a bridge to future discoveries, here referring to beta decay in general. I don't need to sort the beta decays by rarity.

Another great video, very well made and informative

Thanks a lot for the documentary..
It’s just amazing what these scientists had achieved.
Fascinating video as always. Keep it up!
Interesting. I didn't know this history. Thanks
Good info🎉
Well made video.
Profound

Good show.
and all these people had a GLOWING personality's
PLUH!
