Not the person you're replying to but:
- Yes, managing your relationship with your coworkers will be helpful at all stages of your career. You're not managing them, you're managing your relationship with them. It helps you listen, ask simple questions about who they are and listen. You don't have to care, you only have to share a little. You're not building a friendship unless you want to. You're cultivating a positive relationship so that they know they can depend on you when they need it.
- Yes, exhausting. It's called masking and everybody whether they are neuro divergent or not does it. Some people find it trivial, some find it nearly impossible. My wife can tell the difference between my work voice and my regular voice because at work I'm masking. I've been working on bringing the two closer together because I've found it is beneficial to my career to be more myself.
Two more reasons not yet mentioned:
It is close to a population center (Phoenix) keeping latency low to customers. Getting customers off the public Internet quickly and into your private network fast is best for a lot of reasons.
Cheap and abundant solar power. Data centers are extremely power hungry and power lines are expensive so companies like Amazon almost always secure abundant power rights before building. Google built their first data center in The Dalles Oregon because an aluminum smelter had gone belly up and left a bunch of capacity unclaimed in a local hydroelectric dam.
