1) It’s clear that the standard model is an incomplete model, due to some small discrepancies between theory and observation.

2) Large-scale particle physics experiments are very expensive and depend on government funding, and politicians must be persuaded to allocate funds.

The nightmare scenario for particle physicists is that funding bodies get bored of the lack of exciting new results before the known discrepancies in the standard model are resolved, cease funding particle physics experiments, and the discrepancies are never resolved.
