It would be nice to see the statistics: what is the distribution of aliquot sequences lengths before they reach 20 digits the first time, 30 digits the first time, and so on. My impression is, if we extend all the sequences below 1 million (or three million) to 200 digits, we will have many more sequences of length bigger than 10000.

Here are several milestones which were recently (and not so recently) achieved:
Apart from that, there are only two sequences below 1e5 that have not reached 150 digits yet: 29640 and 77392.

All sequences below 1e5 reach 150 digits at least once.
