Indeed, I myself worked for one such niche high tech machinery German company. The problem is, due to the thin margins in these hardware gigs, the salaries are piss poor compared to the skills needed (M.Sc. and up) as even making iOS Apps paid better. Only the execs and the couple of grey beards who were with the company since its inception were well paid, everyone else not so much.
That's the reason youngsters aren't gravitating towards these gigs anymore and prefer to be web devs instead. The margins are higher and the entry bar lower.
I'm not saying they'll go bust tomorrow, not at all, I'm just saying they don't have an easy future ahead, due to low margins and unattractive career paths for youngsters, especially once their patents expire and China will be able to make the same stuff at half price. That's why the UK's decision to focus on services/consulting is a better long term bet IMHO.
