If you use the dictionary definition (ridiculous = deserving or inviting derision or mockery; absurd)
then I personally disagree with your claim, for the following reason.

This is not a ridiculous statement if 

1) one is thinking of formalising e.g. analysis,

2) one is not used to serious/every-day programming (where LaTeX does not count).

There are a number of mathematicians satisfying conditions 1) and 2).  

To be more precise, for many people there is a steep learning curve involved in formalising mathematics, 
while just getting everything installed on one’s computer is already non-trivial.   

As a personal example, as recently as 2019, I could not get a real answer to the question

“How do you define open sets (in formalised math)?”

The answer was always:

“What do you want to do?”

This is not exactly helpful in bringing people to The Cause.  

My point is that novices and specialists have a lot of trouble 
talking to each other (as is often the case), and one should not 
immediately dismiss the qualms of either as ‘ridiculous’.

That is indeed absurd, unless arguments were given.

That is indeed a good point.  

Best,

Sam
