I find the article is badly written. Being a lawyer, a coder and interested in Legal Tech, I still find it hard to read or unterstand some sentences/sections. The author also falls short of mentioning any specific workflows that could be automated (which there are many) or any specific programs or companies that are really changing the legal landscape (which there are not many).
From my experience real AI Legal Tech is yet rarely used (at least in the European legal market). And I have yet to see a company I trust that will change that soon.
