I don't really believe this. Fund some open access initiatives or something and your money will go a lot further.

The vast majority just don't have a use case where "LaTeX-2030" is going to help, and this wouldn't make much difference to them. I'm a mathematician and I write papers in LaTeX every day. Sure I could benefit from programability occasionally, but it's just not a serious problem. If I need to automatically generate a table or something, I have a Python script output LaTeX, it takes me 30 seconds.

Obviously there are some uses cases where it would make a big difference, but there just aren't very many in the grand scheme. We already have LaTeX3 which lets you do scripting, and lualatex. The fact that basically nobody uses either gives you a sense of how much the general community wants this.
