While futurists are always wrong about details like fashion/styling, how widespread a technology will be and how it will be used, they are rarely if ever wrong about capability. i.e. what will become technologically *possible*. To whit:
1. Seasteading is a thing now, the Maldives is moving essentially their entire country onto floating platforms and there now exist two cruise ships one can buy a full time residence on: The World, and the Satoshi. https://aboardtheworld.com/
2. Dating website algorithms exist. How effective are they? Your mileage may vary.
3. Jetpacks exist. Not just the water powered ones, but actual proper jet powered harnesses and platforms you stand on, levitated by small jet engines, such as the Zapata EZFly and the Jet Suit.
4. Portable air conditioners are readily available at many stores. They're inefficient, but they exist.
5. This is entirely possible from an engineering standpoint and in fact was implemented in cities like New York and Philadelphia for mail delivery in the 20s and 30s. It was discontinued due to delivery by truck proving more economical than the constant tube repairs.
6. Agribotics absolutely is an emerging field. Many robotic farming machines exist and are on sale today: https://interestingengineering.com/9-robots-that-are-invading-the-agriculture-industry
7. As you point out, this one came true in the form of the Kindle and other e-readers, the only thing they got wrong is the size and appearance. Their prediction was actually too conservative, we were able to do better than they thought.
8. While we're not there yet, there has been indisputable progress in this direction. It's not really accurate to say cars cannot self drive, rather that they don't yet do a good enough job at it.
9. These exist in China right now. Here's one delivering fried chicken: https://thelastdriverlicenseholder.com/2020/11/24/kfc-delivery-robots-in-shanghai/
10. Domes like this one for creating tropical conditions inside, in regions with cold nasty weather, have existed for some time: https://alexbeyman.medium.com/surviving-in-domes-on-a-warmer-earth-will-prepare-us-for-mars-59f237c6871?source=user_profile---------0----------------------------
11. The Canadian Avrocar demonstrated that saucer shaped VTOL aircraft are possible, just not very fast, maneuverable or fuel efficient: https://en.wikipedia.org/wiki/Avro_Canada_VZ-9_Avrocar
Helper monkeys for the blind/parapelegic and other service animals absolutely do exist. I am confused that you haven't heard of them.
Bonus 2: Electric cars are now commonly designed around "skateboard" platforms for ease of basing many different models and styles of vehicle on the same shared drivetrain
