Never thought about Amazon, but I did completely expect Facebook to tank. Apparently I underestimated their level of deviousness and willingness to manipulate people.

I don't even think I want to take a guess on OpenAI. I just don't think they can deliver a good product that aligns with my own moral compass, while trying to generate profit for shareholders.

For the first year or more after IPO Facebook's stock was completely flat. I bought around the IPO and it went down significantly and only recovered after a couple years. I stupidly sold at that point once I'd had about a 10 or 15% gain.
