It's fairly well accepted that we face a significant shortage in cyber-security talent, not just in the UK but globally. High-level agencies like the NCSC have gone on record that they find it increasingly difficult to recruit specialists - but I've seen it throughout the industry, from entry-level positons up.
The article mentions the difficulty in filling highly-skilled roles, but it's interesting the commentary by a US state official, that their main concern is “the part-time registrar who is also the town attorney and the town accountant and is working out of a 17th century jail” - tying neatly into my previous piece on voter-fraud and electoral machine hacking.
An interesting potential solution to this problem is put forward by the author, that small-scale conscription into a national service dedicated to cyber-defense could produce a body of skilled, trained young people; mirroring the way in which Israel benefits in innovation by virtue of its output from the elite Unit 8200.
