The word becoming implies it isn't one as of now.

The median age of the population in the US is 39. The median age of the Senate is 65. In other countries 65 is retirement age. So you could say, yes "America" (the US) is a gerontocracy.

The Latin word "senate" originally mean "council of elders", and is transparently related to "senex", meaning "old man". It's pretty ordinary in human society for the decision-makers to be primarily comprised of old people who have lived a long time and seen a lot.

Roman senators were 40-50

From an alternative source, that varied:

  What period are we talking about? In the monarchy, the Senate were all men who could no longer serve in the military, generally believed to be at least 60 or older, and generally numbered 100-200 men.

  With Sulla's reforms in the 1st century BCE, you had a minimum age of 31, total population of about 600, with about 5% of that group needing replacement every year. The "elder statesmen" then were for the most part those in their 40s and 50s, with the handful of Senators who were older and had beaten the odds still around, [ ... ]

  By the Flavian dynasty, if you had military experience you could join as early as 25 and the body was as many as 900-1200 by the end of the 2nd century CE, filled as the Emperor saw fit.

We really have no clue how it worked. If anything it probably was more related to being a head of a prominent clan/family.

The Roman historian Titus Livius (Livy's History of Rome (and various other names)) roughly covered how it worked from the founding through until 293 BC and from 219 to 166 BC.

The periods 293 through 219 BC and 166 to 9 BC are vague because of missing Livy volumes and lesser (or no) alternative sources for those ranges.

Aside from age, being a (primary major family) Patrician was a factor for some of the Roman Kingdom, at other times the pool expanded to include minor Patrician families. During the Kingdom the Senate largely worked as an advisory council to the king, grinding through legislative details, and more or less being responsible for the election of new kings (variously with or without input from "the people").

The current consensus is that Livy only had a very vague understanding of the early republic let alone the royal period since his narrative frequently conflicts with archeological evidence and other sources. Basically he was constantly projecting the late republican system onto much older periods and implying it barely developed or changed over the years while there is strong evidence to the contrary.

> Patrician was a factor

We don’t really understand the patrician vs plebeian split and how it functioned before or during the founding of the republic. Again there is evidence it was only fully established decades later.
