About としたら・とすれば・とすると
When partnered with several of the assumption based expressions that are used in Japanese, the case marking particle と may be used to show a hypothesis about a certain result. This is one of the result highlighting uses of と. Structures that may be seen are as follows:
(A) としたら (B) - When (A) is the result, (B).
(A) とすれば (B) - If the result is (A), (B).
(A) とすると (B) - A result of (A) will be (B).
Although these nuances are slightly different, realistically they are used in almost exactly the same way, to express a possible (undetermined) result. This can be translated to 'assuming that (A)', or 'if it were the case that (A)'.
To use these expressions, simply attach と and your chosen variation of したら to the end of any verb/い-Adjective, or noun/な-Adjective followed by だ.

Hmmm, or is it “will have”, for the past in the future??? Will we ever have figured this out, at some point, especially if we hadn’t have had this current conversation, presently, in the past of the future!? Probably we will have not have had! Won’t you have not have had to have agreed, by then, at some point, I know not when?

Conversations like this make it plainly obvious why English is a stupid language haha.
Yep, that’s pretty much it. If the speaker didn’t specify exactly, it’s because they didn’t think it was important enough to do so, or they thought it was evident already.
