It's worth competing in any industry if the numbers work out. My main point was that the extremely high margin and lack of competition in SaaS is not likely to persist over time (without a defensible moat/high cost of switching). It's a better time than ever to create a SaaS with low cost overhead. If you leverage serverless and strong design, you can build extremely useful and far-reaching products with a handful of people. No longer do you need hundreds or thousands of people to do this. Then operational cost is low, and revenue required for breakeven/profit is low too.
