If you're going into a field where you need a solid technical foundation the knowledge is what matters. But if you're going into an unrelated domain like most college grads who enter non-technical, white-collar jobs the diploma is the return because the coursework has no direct relevance to the profession, but employers will filter out applicants without degrees.
Someone with a bachelors in history has a much higher likelihood of being hired for an entry level sales role for example, than someone without one. But that bachelors isn't conferring any unique knowledge about sales.
You're talking about rigorous fields where practitioners need a solid technical base. There are lots of white-collar jobs that really don't require a college education but employers will filter out applicants with degrees.
Even well-known product lead companies like Atlassian employ sales reps, especially at the enterprise and strategic levels, because demonstrating value to the end user is only a part of the sales process. There's lots of additional work that's closer to project management that's required to close a deal. It's identifying and aligning stakeholders, helping to justify budget by putting together a business case for leadership and finance teams who won't directly interface with the product and need to be sold on it's value. This is the sort of thing high level business to business sales reps spend a ton of time doing.
That depends what sort of timeline you're looking at. I wouldn't be surprised if the price fell more, but the markets are forward looking and long term they're a key player in the space.
