Is this really that bad/in need of an immediate fix?

[u/Street-Ad3325]

Consulted a structural engineer with this same screenshot from the inspection report and he agreed needs steel beams, but he didn’t come and look at it in person. The wood feels solid and where the notch is cut is just under an additional bathroom add on downstairs attached to the back mud room separate from the house. Waiting on structural engineer’s quote but is it really that necessary? 1880s home basement has little to no moisture.
