Making yourself immortal must be a unique process for each being for security reasons. You do not ever want to be subject to mind-control technology, for example.

Another interest is time-bending technology.
For example acceleration of your own local reference frame within a confined area to augment your productivity.
You may appear to age more quickly to those you know unless you make yourself both immortal and very alive by generating your own life-energy within your physical form.

Others may be interested in evolving their physical forms with quantum biology and alchemy.

A key interest for some is using singularly generator technology for electrical power generation.

The highest and lowest dimensions are easy for me. The rest of it I must translate to be comprehensible to others.
Where many see paradoxes I see unity.

Usually everything at once.
