should be + ing vs. should + bare infinitive

Hi,

1) We should be specializing in semiconductors.
2) We should specialize in semiconductors.

They look similar to me. If there's any difference, it would be very slight. What is it? Would you let me know?

Thanks in advance,

The difference is slight, but the progressive indicates this is something that should already be under way.

Oh, thank you for this quick reply, Mordant! That kind of differences are not easy to catch for an ESL learner like me.
