> Why do people think they can "play with new technologies" at work, which is wasting not only company money, but other people's time as well.

Because that is where new ideas, new approaches, innovation and knowledge creation happen? In software, like many other knowledge-work professions, you can't just put in a few years at university and then stay on top of your game by simply showing up every day for 40 years. The daily challenges are too diverse and change too quickly. Continuing education is a significant part of staying in the game, mixed with daily application of this knowledge.

Think about it this way - if you're a high-value developer, you've already put in thousands of hours of R&D and practiced with numerous technologies. Much of it on your own time, much on a previous employer's time. This knowledge is the basis of your current skillset. It's why companies pay you a salary. It's how you adapt to novel challenges in daily work for which you, by definition, require a larger body of knowledge to draw from. You know best how to build that body of knowledge.

Some companies are apparently more than willing to reap the benefits of R&D that was done on someone else's watch. But when it comes time to allow R&D on their time, suddenly it's "wasted" and derided as "play". The only thing that's wasted here is the developer's talent. When the "adults in the workplace" behave like this, making arbitrary engineering decisions about what is legitimate work vs play time - despite lacking the engineering context or credentials to make such a bold determination - that reeks of unprofessional behavior.

It would be like me micromanaging a lawyer's document list in preparation for their case. Or me telling a doctor which medical journals they should/should not be keeping up with. I'm not qualified! So I shut up and let them work, and put my trust in their deep knowledge and hard-gained experience. That's professional.
