Um... No.

Do they know at what rate it changes color if I keep it several days ?

Just as much as Google News is.

Books: The Bourne trilogy, which, contrary to the movies, were very entertaining.

Peopleâ(TM)s speech is largely just prediction too. People donâ(TM)t generally think out entire monologues first, they start talking and go with it.

Everyone is using OpenJDK these days, nobody in their right mind would pay for their licensing.

The planet may disagree though.

You say that like thereâ(TM)s a possibility they arenâ(TM)t corrupt. Hereâ(TM)s a hint, they are approving mergers based on cancelling DEI programs, what does DEI have to do with this? Nothing but criminals gonna criminal.

A plumber can make art while plumbing. A truck driver can make art while driving. Yet that is not the first purpose of their jobs. Hence, in general, a truck driver is not an artist. Of course, nothing prevents a truck driver from being an artist.

Same for engineering (software here). Our job is to build / maintain systems. Not to create art. Now, we can create art in the process, of course, just like everyone else. But no, engineering is not art by any stretch of the imagination.

Art: the expression or application of human creative skill and imagination, typically in a visual form such as painting or sculpture, producing works to be appreciated primarily for their beauty or emotional power.

Engineering is an activity that has a practical goal: Build a plane, make a website, make this piece of code scale. Not activities primarily appreciated for their beauty or emotional power.

If your program will be up for days (think a server, a browser, etc...), the startup time can easily become negligible.

Well, each thread uses its own buffer, so there is no issue, is there ? They can then switch buffers when they feel the need to.

Engineering is inherently a creative job, so is researcher, and many others. That does not make it art.

Java is slow to start, because the JVM is a beast that takes its sweet time to get up to speed. After this hit, the type of code you are talking about will be about 5 to 10 % slower, which might be acceptable or not depending of your requirements and the value you put in all that Java provides and C does not.
