The problem is that if you’re in academia, you have to intimately know what the corporate world is doing out in the business world and how that transfers to corporate dollars. These are businesses. They expect to be compensated and understood by academics.
They expect future employees to have the benefit of professors who have worked in the industry. Internships are not the same.
You don’t get to “stay and play” as a Ph.D. Limiting your work to research. That’s for professors who have a history of teaching for 25+ years and have embedded grants.
The departments on university campuses have very finite budgets for each department.
The university tells you what to teach and when. They tell you if your proposal for new equipment will be funded.
You will be expected to submit various grant proposals. And most of the time, you need to do this to get any new equipment in your lab while teaching, writing and submitting constantly with low pay. Grant Requests are often rejected.
You have to teach classes based on, not only the subject matter but also your working experiences and how to apply what has been learned in the classroom to the real world employers. Students and staff expect you to have links/ resources to corporate employers.
My daughter can immediately refer a junior executive to a work colleague. Because of her history of professional experiences, working alongside colleagues, she has a strong network of contacts.
Son is developing his network. He has already established himself in a specific area of CS.
While being in a vacuum, on a campus, and never really “working” in this industry, how could you legitimately use your limited work experience resources to teach others about this industry?
If you have no “real world” long term work experiences, then you can’t really expect to be effective in teaching students what they will be asked to do in their CS work environments.
Both my daughter and son have a LOT of business meetings. They discuss: clients, budget ramifications of contracts, labor hour usages, and the cogs of getting a project done and submitted for review.
Yes, they have had internships, but these are limited by time and security issues. Future employers expect their employees to have significant educational experiences and be able to adapt to work environments based on the conditions presented by their corporate clients.
If you’re an international student, you’re not eligible for security clearance. How will you explain to future students, without real world knowledge nor experience, and no concept of what it’s like to meet the industry security requirements?
