I saw that. I don't know what PGP is and I don't have firsthand experience with BART, though I inferred her remarks were not intended to say anything nice about it. Perhaps you could elaborate for me?
Well, PGP is an email encryption layer that's 20 years old and was very enthusiastically adopted by the privacy community. It actually has some uses, e.g., Edward Snowden used it to communicate with Laura Poitras. But it's too complicated for the masses and nobody uses it. Kinda like bitcoin.
As for BART, I only took the train a few times in my life so I can't really elaborate on that.
Thank you. The info on PGP is helpful. There is enough criticism of BART online that I can get the general idea that comparing something to it is not likely to be a positive.
