It’s enterprise software, so by definition it “sucks” to the average developer due to its complexity and accumulated tech debt. Show me one software tool that has as much functionality as SAP and does not suck by your standards. Unicorns like Slack have better UI/UX because they solve a conceptually much simpler problem. Maybe you could say it’s better to find a large market that can be addressed with a simple tool, but being in a large market with an incredibly complex product also has its benefits. I doubt for example that SAP will be disrupted by a unicorn with better UI because the upfront cost of building the same functionality that SAP offers (and which is not superfluous) is horrendously high. Regarding Slack I can absolutely imagine that it will be disrupted in the near future, because it’s conceptually a much simpler product.
