Lawsuits and bad press.

HR represents the company. Where your goals and the company's aligns, they can be helpful. Where they diverge, perhaps less so.

I think a lot of these sorts of articles discount the idea that your goals and the company's will frequently align. For example, if you're being harassed, it's very often in the company's interest to stop that happening. It will cause you and perhaps more people to quit if they don't, and there might be legal risk. If you're productive and impactful, it's often in their interest to help you with career goals.

Things get muddy when you e.g. have a problem with your manager, or folks above you. Then HR has to determine which side to back based on what they feel is most helpful to the company's goals, or what is less risky. But even then, consider that they might want to avoid bad press, lawsuits, etc. If the situation is bad for you, it could be bad for the company too, but it's worth thinking about deeply before going to HR.

That doesn't make sense. Math equations are expressions of ideas. They can be fallible as much as anything else. Just because 1+1=3 is an equation doesn't make it true.

You say "... the way they have literally arrested people for tweets", as if "tweets" is a special "thing" , but it's just communication. If something is illegal to say, it stands to reason that it would be illegal to say through the medium of a tweet. Is it less ridiculous to arrest people from what they write in a blog post or what they say on the street than what they say in a tweet?

It seems like one should either take free speech absolutist approach and say speech should never be illegal, or accept that some speech is illegal which would obviously mean that it's illegal even on Twitter. But you're not the first person I've seen who seemingly find it extra ridiculous to react to something someone tweeted, as if publishing a tweet or a series of tweets is not an act of speech, and I don't understand it.

The area of study you're looking for is called Kinematics and if you do want to go down the building an arm route, you'll need a more than passing familiarity with Electronics and microcontrollers, since you like python, a Raspberry Pi is probably the best choice.

If you truly want to learn, I suggest joining a local FRC Robotics team as a new/junior mentor. If you simply ask the students to show you what they have been working on, you may be inspired to join in and help. You'll learn together... mechanical, electrical, programming, etc.

I've been volunteering as a FIRST mentor for the last nine years and have learned more about robotics from the students than I did in my master's program or on my own.
