Nonsense, No/lo-code is the polar opposite of UML, No-code is the ultimate Agile, it’s exciting and fun to build with, because it’s alive, because it executes immediately, resulting in a powerful iterative feedback loop. UML is static and tedious to build, because any gratification is delayed so far into the future. I know because I’ve done both, in fact I’ve invested all of my wealth (many millions) into developing a No-code ERP/CRM platform and it’s incredible - will launch this year.
