Same site as the OP has an article stating Tesla makes it difficult, and if you put 50k in 8 years ago and obtain 50k now, I think you lost a lot of money. I have no opinion on the process itself though, I don’t know enough about Tesla as I’m only interested in the engineering, just wanted to point out the inflation losses.

This is a textbook sunk cost fallacy.

I am curious - are you familiar with inflation?

I'm not sure you're familiar with it either, or I've missed how on earth it applies in this situation.

Are you? Because I don't think it has anything to do with what we were discussing.

No it isn't. It's textbook time value of money, which is a real thing.

And if you don't think so, please give me $50k, I'll give you back $50.001 in 8 years, a dollar more! You'll come out ahead, right?
