If you're writing on your personal blog then take all of this with the size of salt crystal you feel it deserves. Personally, that's about the size of an Acme safe hanging over a cliff waiting for an unsuspecting listicle writer^h^hcoyote.

The biggest change from then to now is probably the amount of solid state electronics onboard. That's ridden roughly the same curve as other industrial and commercial applications.

Example, since you edited to add examples: I have several business bank accounts and far too many Stripe accounts all registered as sole prop. I haven't had to take a loan but I do have a sole prop credit card. My understanding is that even with an LLC a bank is going to require a personal guarantee for a loan.

Anyone can get an EIN for their sole proprietorship business (just one, though) and use it on tax forms.

A formal business structure is good (but not required!) if you have employees and/or business partners, or if your attorney tells you you need one. IME as a solo entrepreneur an LLC (or two, in my case) just invited more paperwork into my life.

You know what actually functionally limits liability as a solo business? Good contracts backed up with business insurance.

Developing a voice comes naturally as you go through the pain of being a terrible writer to eventually being mediocre. Accepting the LLM's words is actively harmful to that process because it lets you skip over the part where you read over what you wrote and rewrite until it doesn't suck as much.

I mean, you do you. I'm not your dad.

"Duh, of course Mars has canals."

Testing the "obvious", "duh" things is incredibly valuable science. It provides a more solid foundation on which to build because it reduces the assumption space.

(also I don't think Tourette's is fair to include in that set but whatever)

Doesn't mean he's wrong.
