Silicon chips will be made at well funded makerspaces. Thanks to advances in electron beam lithography, structured light projection, and other advances. You'll be able to design a custom chip, and try out the prototype a few days later, depending on complexity.
Thanks to advances in technique, ground loop based heat pump systems will find their way into use in most new buildings. This will allow for the use of solar and other renewable power on a far wider scale, making the grid a welcome way to share power when needed, instead of a unidirectional network.
Parallel processing will find its way down to the bit level. Instead of fixed width architectures, you'll be able to scale the precision of a calculation as much as is needed, allowing the most efficient use of silicon (or its replacement)
Quantum computing will be an interesting research area.
Thanks to ubiquitous internet, computer hardware, software, and advances in both additive and subtractive manufacturing, it'll be possible to build almost anything in the home, provided the elements to do so (or acceptable substitutes) are on hand. It will be well within the capability of an enthusiast to build machines that can make more of themselves. It's the first 3d printer, taken to the limit.
Either we'll all enjoy secure general purpose computing, thanks to the capability object model form the 1970s... or we'll still be complaining about hacking incidents (unless laws prevent doing so)
I hope you all are having fun in that future.
