I would also argue that the successful way that Ireland has brought big companies to the country hasn't yet resulted in the spin off of benefits that the presence of such companies has had in other areas.
Unfortunately, these companies were brought over by accountants, not engineers..
In so far as, Ireland gave them an opportunity to target EU market (& tax deals) which meant their staff is mostly non engineering (customer service/finance/legal).
The big mistake Ireland made (back then) was not ensuring some of their core business functionalities _had_ to be present in Ireland (i.e. engineering)
A lot less new tech companies built by accountants and customer support staff compared to engineers.
These are just a few off the top of my head, but the history is really interesting. A good bit of it has to do with Shannon, which actually served as inspiration for Shenzen believe it not!
I've been tempted to write up this history for quite a while because it's not really well known, and even despite being in STEM myself was quite surprised when I found out Analog Devices actually do design and manufacturing here and were making chips for Apple and Waymo!
