I’d argue there are plenty of other places in the US that fit that bill, but Intel having built fabs in Arizona for a long time is an important point on its own

I’d argue there are plenty of other places in the US that fit that bill, but Intel having built fabs in Arizona for a long time is an important point on its own. Because of local history that’s where expertise for running a fab exists, so they’ll have a better supply of workers if they keep building fabs in Arizona than trying it out somewhere new.
