I’d like to join those asking “who is Sahil?”. And to answer some points:
A term incorporating soloware and groupware (in this new meaning of “groupware”) is probnably nicheware
SaaS on open source is a thing for ages now. SaaS is mostly not about “can’t have the code” but rather “can’t be bothered to run and support it”. There is a lot of expense, in money and time, needed to run existingm legitimately available code reliably and to resolve issues speedily. So I would not expect any explosion of nichware to bite into “*aaS” as a concept; rather, SaaS platforms might adapt to serve nicheware, and/or there might be some shifting from SaaS to PaaS/IaaS (to take an AI example, a per-token billed standard inference endpoint is SaaS; a serverless endpoint to serve your custom model, billed by the second of activity, is PaaS if not IaaS).
This is fun—I was dropped here by a search, did not realize the date of the post, and read a while before realising this—was kinda curious about the model and system prompts behind “Miley Cyrus”. I guess “Miley” successfully passes the reverse Tur[n]ing test.
