Ask HN: What product or service is conceptually great but poorly executed?

Cyberpunk 2077. Stunning graphics and soundtrack, a setting with potential. Serious performance issues, lack of competent AI, many other corners cut.

Management did not listen to people "in the trenches", should have delayed it at least 1 year.

Google Stadia

Siri/Alexa/Google Assistant

Everything "smart home"

5G LTE

USB-C

I think both google stadia and the nvidia competitor are basically the future of gaming, but I think someone else is going to do it right/better and win 90% of the market.

I agree that they're the future.

I disagree that anyone will get 90%. I think we'll see the same frustrating, fractured environment that we already have in video streaming.
