Testing whether I'd ever have access to a time-machine in the future I have stood at several well-defined locations, at well-defined dates. I have memorized these date-location combinations over the years. There are several because I refined the process over the years to take account of locations that may not be accessible in the future, due to sea-level rises etc (i.e. working on the principle of H.G. Wells' physically-bound machine, and not a TARDIS).

Had I been successful in gaining access to a time machine, I would have already come back to meet myself at the very time I made the decision to mark the time and location. I have not ever done this.

My conclusions (so far) are that: a time machine will not be invented in my lifetime, my future self is avoiding a time travel paradox, or early-onset dementia is preventing my future self from remembering a location-time correctly.

Hoping that is the later, I continue to memorize these placetimes.

Why first contact hasnt been made

The universe is around 15 billion years old. Earth is around 4 billion years old. Humanity has existed in its present form for a few tens of thousands of years. We've only had radio for around 100 years. In all likelihood, we will have created a computerized intelligence within another 100 years.

A computerized intelligence would be effectively immortal, and capable of making improvements to its own code, thus increasing its own intelligence, even if only by working with backups of itself. A society of such intelligences (or even a single individual) could potentially sustain itself and explore the universe for millions or even billions of years, and do so using vehicles that don't include any kind of life support.

In other words, in the eyes of a universe filled with multimillion year old super intelligent computers, biological intelligence would be considered a transitional species, and first contact would wait until the transition had been completed.
