I would only upgrade to FSD with the following constraints:
1. Not buying anything else until it's implemented, working, and available. Not paying for any future promises anymore.
2. If/when that happens, I'll pay only as much as the difference between what I paid for EAP ($5K) and the total new price for FSD (currently $6K). Thus, if it were available right now, was working, and was available, I'd pay $1K, not a penny more.
3. HW 3.0 computer has to be available and ready for immediate install. Not buying it if I have to wait, get on a list, etc. My P3D is 9 months old, still doesn't have a spoiler. A spoiler. A plastic piece that sticks on with tape. You can't get that to me in 9 months, and I'm supposed to trust that you'll have HW 3 AP computers for everyone? GTFO.
