Pros
There were once many, but now I can't think of any
Cons
The cold hard reality is that SAS is a slowly dying company and nothing can turn it around at this point. Open source now completely dominates the space that SAS once dominates. The facts are clear, SAS usage has been in steady decline for years and that decline is accelerating. SAS tried to reinvent itself with Viya, but the uptake has been abysmal. The best measure of this, is to do a LinkedIn job search and compare against the competition such as Python... I just checked now... "SAS Viya".....141 jobs in the entire US. 18 in India. 5 in China. 30 in the UK. "Python"....887,000 jobs in the US, 164,000 in India, 559,000 in China, 128,000 in UK. Those numbers make pretty grim reading for SAS. Who would bother learning Viya? SAS spending money on further development of Viya is throwing money away. It's a poor product that nobody wants. What I hear from my former colleagues in sales/presales who are still there, is that the IPO plans have turned the place into a nightmare bureaucracy with layers upon layer of additional process that adds no value to customers. It's impossible to get anything done. Morale is terrible. Politics is becoming unbearable. One said to me that "it's a sinking ship and the rats are eating each other"
