I think the big issue with workforce is getting people onto the career path. Semiconductor manufacturing has traditionally been localised to Asian countries, and even if people from the west would like to specialise with that they just don't have as many options. If Europe puts large investments into the industry and recruits out of universities I think they could definitely build up a strong workforce. Maybe not quite in the timeframe they're aiming for, but there's something to be said for ambitious aims to encourage a harder push.
