Affordability was and is a difficult and complex issue. What has definitely changed is that the definition of SOTA has been corrupted by the rise of boutique products that are super expensive but may or may not be any more SOTA than less, but still, expensive products. Personally, I do not feel left out by not being able to afford the most expensive.Of course SOTA reference gear then was something an average PhD likely could afford. Now I think you need to be a venture capitalist or banker or something.
